Receiving an unexpected letter showing PO Box 5622 Manchester can be confusing, particularly if the envelope appears to relate to banking, money or an account you do not immediately recognise.
Searches for the address frequently connect it with NatWest and Royal Bank of Scotland correspondence, but the return address on its own is not enough to prove who sent a particular letter.
The safest approach is therefore neither to assume the letter is fraudulent nor to assume it is genuine.
Check the organisation named inside, compare the reference with your own records and contact the supposed sender independently if the letter asks you to make a payment, provide information or take urgent action.
What Is PO Box 5622 Manchester?
A PO Box is a postal address that allows mail to be handled without using a conventional public-facing street address.
Royal Mail currently offers both PO Box Deliver, where mail is forwarded to the address registered for the service, and PO Box Collect, where mail is held for collection.
Royal Mail also promotes PO Boxes to businesses as a way to provide a professional mailing address while keeping another address private.
That helps explain why a bank, financial services business or large organisation might use a PO Box as part of centralised correspondence processing.
It does not, however, mean there is a customer-facing office called “PO Box 5622” that you can visit.
The postcode M61 0WZ is commonly displayed alongside references to PO Box 5622.
There have been conflicting entries about the postcode’s historical status in third-party postcode databases, so its status should not be used as an authenticity test.
More importantly, an unusual postcode does not prove that a letter is fraudulent, just as a familiar postcode does not prove it is genuine.
Who Actually Uses PO Box 5622 Manchester?
Public reports strongly associate PO Box 5622 Manchester with correspondence connected to Royal Bank of Scotland and NatWest, but the available evidence does not justify stating that either bank exclusively owns or uses the address.
That distinction matters.
Royal Bank of Scotland is part of NatWest Group, and both brands appear in NatWest Group’s official current brand portfolio.
This makes shared or related administrative arrangements plausible, but it does not establish that every envelope carrying PO Box 5622 was generated by NatWest Group.
No publicly available NatWest or RBS contact page we checked identifies PO Box 5622 Manchester as the bank’s general public contact address.
Customers should therefore use the postal or contact details supplied for their specific product on the official bank website rather than sending sensitive correspondence to PO Box 5622 simply because it appeared on an envelope.
What does the real-world evidence show?
There is also some anecdotal evidence.
A December 2024 comment on UK Postcode stated that the contributor had received what they described as an accurate, genuine Royal Bank of Scotland statement in an envelope carrying the return address PO Box 5622, Manchester, M61 0WZ.
That report is useful because it demonstrates at least one claimed real-world instance of authentic RBS correspondence displaying the address.
It is not official confirmation, however. A reader comment cannot establish ownership of the PO Box or prove that another letter using the same address is genuine.
Is a Letter From PO Box 5622 Manchester a Debt Letter?

Not necessarily.
One of the biggest mistakes is assuming that an unfamiliar financial return address automatically means debt collection.
A return address tells you where an undelivered item may be routed. It does not tell you what is inside the envelope or establish that the recipient owes money.
A letter displaying PO Box 5622 could potentially concern routine banking administration, account information, product changes, a response to a previous enquiry or another financial matter. If the account has fallen behind, the correspondence could also relate to arrears.
These categories should not be confused:
| Letter type | What it may contain |
| Routine account correspondence | Statements, administrative notices or account information |
| Product or terms update | Changes to rates, fees, account conditions or services |
| Arrears communication | Missed-payment information, the amount outstanding and options for contacting the lender |
| Default-related communication | More formal information about persistent arrears or action being considered |
| Third-party debt collection letter | Details of a creditor, claimed balance and instructions for dealing with a collection company |
A genuine arrears-related letter would normally give enough information for you to identify the account involved, such as a reference, product information or amount due. You should compare those details with records you already hold before taking action.
UK Business Magazine’s coverage of letters from PO Box 61278 London illustrates the same important principle: the postal return address is not, by itself, proof that a debt exists or that the person receiving the envelope owes the amount being discussed.
If you do not recognise a supposed debt, do not make a payment simply because the letter appears formal. Independently contact the named lender and ask it to confirm the reference and reason for the correspondence.
How Can You Identify the Real Sender?
Instead of focusing only on the PO Box, examine the whole document.
Start with the organisation’s name and branding, but remember that logos can be copied.
More useful clues include whether the letter refers accurately to a product you actually hold and whether its account or reference information matches previous genuine correspondence.
Check:
- The named organisation: Does the letter clearly identify NatWest, RBS or another business?
- Your name: Is it addressed correctly, including any business name where relevant?
- The product: Does it mention an account, card, loan or service you genuinely have?
- The reference: Does it resemble references shown on previous authentic statements or correspondence?
- The reason for contact: Does the request make sense based on recent activity on your account?
- The website: If a domain is printed, type the bank’s official domain into your browser independently rather than following an unfamiliar link.
- Payment instructions: Be particularly cautious if the letter suddenly instructs you to pay into a new account.
- Telephone details: Check any number against the bank’s independently accessed official contact page.
- QR codes: Do not automatically scan a QR code merely because the letter carries convincing branding.
The more sensitive the action requested, the more important independent verification becomes.
What Is the Phone Number for PO Box 5622 Manchester?
There is no customer-service telephone number belonging to the PO Box itself. A PO Box is a postal facility, not a customer support department.
If the letter claims to be from NatWest, use the bank’s official NatWest contact page.
As checked on 5 October 2026, NatWest lists 03457 888 444 for general personal banking enquiries, while separate fraud numbers apply depending on the product involved. NatWest’s contact page also provides mobile-app, business, card and overseas routes.
For Royal Bank of Scotland, use the official RBS contact page. RBS currently lists 03457 242 424 for general personal telephone banking, with different numbers for cards, business customers and fraud-related matters.
Because banking contact numbers can change and different products use different teams, checking the official website at the time you call is preferable to trusting a telephone number printed on an unexpected letter.
How Can You Tell a Genuine Bank Letter From a Suspicious One?
No single visual feature proves authenticity. Scammers can copy bank logos, formatting, addresses and terminology.
Look instead at what the letter is asking you to do.
| More consistent with normal correspondence | Warning sign requiring verification |
| Provides information about a recognisable account | Refers to an account or product you have never held |
| Gives a reference you can independently verify | Provides vague or inconsistent references |
| Directs you towards normal official banking channels | Pressures you to call an unfamiliar number immediately |
| Allows you time to verify the issue | Threatens extreme consequences unless you act immediately |
| Uses previously established payment arrangements | Gives completely new payment details unexpectedly |
| Tells you to use secure banking services | Requests passwords, complete PINs or security codes |
| Uses a verifiable bank domain | Includes an unrelated or misspelled web address |
| Provides ordinary ways to contact the bank | Pushes you to scan a QR code before you can supposedly resolve the issue |
NatWest advises customers to check the source of unexpected communications and type official contact information directly into their browser instead of relying on links or QR codes.
It also warns that criminals may impersonate banks, police and other trusted organisations.
Both NatWest and RBS state that they will not ask customers for a full PIN, full password and card-reader codes by text, email or telephone.
A simple scam example
Imagine that you receive a professionally printed NatWest-branded letter carrying PO Box 5622 as the return address.
It says unusual activity has been detected and instructs you to transfer £4,000 to a “protected account” before 5pm. It also gives a telephone number and QR code for immediate verification.
The familiar bank name and postal address do not make that request safe.
NatWest’s security guidance specifically warns customers against being pressured to act urgently and says only criminals will ask customers to move money to a so-called safe account.
Instead of using the letter’s number or QR code, open the NatWest app or independently visit NatWest’s official site.
The same caution is relevant to other reported NatWest-style postal correspondence.
UK Business Magazine’s article on mail linked with PO Box 6034 Westcliff-on-Sea also highlights why bank branding and a plausible return address should be independently checked.
What Should You Do if the Letter Is Addressed to Someone Else?
If the envelope is clearly addressed to a former occupant or another person, it does not mean their account, debt or financial problem has transferred to you.
Do not provide your own banking information simply to try to resolve somebody else’s correspondence.
A practical approach is to leave the letter unopened, cross out your address where appropriate, write “Not known at this address” or “Return to sender” clearly on the envelope and put it back into the postal system.
If letters from the same bank continue arriving, contact the bank through its official channels and explain that the named person does not live at the address.
Receiving correspondence for a former tenant or owner does not by itself indicate that you owe the bank money.
Why Would a Letter From a National Bank Have a Manchester Address?

The city printed in a return address does not necessarily show where your bank account is managed.
Large financial organisations centralise administrative functions. Mail can be printed, returned, sorted or processed in one location while the customer, branch, relationship manager or specialist team is located elsewhere.
For example, someone living in London could receive an account communication using a Manchester return address even though they opened the account elsewhere.
That is one of the practical reasons businesses use PO Boxes: Royal Mail’s service allows mail to be handled through a dedicated postal address rather than exposing or relying upon a particular office or home address.
The Manchester wording should therefore be treated as postal-routing information rather than proof that the employee dealing with your account works in Manchester.
Can You Visit PO Box 5622 Manchester?
No customer should assume PO Box 5622 is a bank branch or publicly accessible NatWest or RBS office.
Royal Mail describes its PO Box service as a way of receiving mail through either delivery to the holder’s nominated address or collection through an appropriate Customer Service Point. That is fundamentally different from a business publishing a branch or reception address for visitors.
If you need face-to-face assistance, use the bank’s official branch-finding service instead.
Likewise, do not use a third-party claim about a Manchester mail centre or Customer Service Point as evidence that PO Box 5622 belongs to a particular bank.
Such claims should be treated as anecdotal unless confirmed by Royal Mail or the financial institution itself.
What Should You Do if You Think the Letter Is Fraudulent?
First, do not use payment details, links, QR codes or contact information in the suspicious document.
Contact the bank independently. If the correspondence claims to be from NatWest, its official fraud service explains how to report suspicious transactions and communications.
Royal Bank of Scotland provides a similar dedicated fraud-reporting route and states that customers who think they have disclosed security or card details should contact it immediately.
If money has been lost or you believe a fraud has occurred, the national reporting system changed recently.
Action Fraud was replaced by Report Fraud on 4 December 2025. People and businesses in England, Wales and Northern Ireland should now use Report Fraud.
The service accepts fraud and cybercrime reports and also provides a route for reporting suspicious communications.
For incidents in Scotland, Report Fraud directs users to Police Scotland. Police Scotland says non-emergency fraud can be reported online, by phone or in person, while 101 is available for non-emergency police contact.
Royal Mail also provides scam guidance. If suspicious material has arrived through your letterbox, its current advice includes completing its online scam-mail form. Its scam centre additionally explains how to report fraudulent messages pretending to be Royal Mail.
Should You Be Worried About PO Box 5622 Manchester?
The address itself is not a reason to panic.
There is credible anecdotal evidence connecting it with genuine RBS correspondence, and NatWest and Royal Bank of Scotland operate within the same banking group.
But there is not enough official public evidence to state that every letter displaying PO Box 5622 Manchester comes from those banks.
Treat the address as one clue, not authentication.
Read the document carefully, check whether the account and reference make sense, and use independently obtained bank contact information before making payments or providing sensitive information.
That approach works whether the letter is a routine statement, an arrears communication, a product update or an attempted impersonation scam.
FAQs About PO Box 5622 Manchester
Is PO Box 5622 Manchester NatWest?
The address has been widely associated with NatWest-related banking correspondence, but we found no public NatWest statement confirming that every letter from this PO Box belongs to NatWest.
Is PO Box 5622 Manchester connected to RBS?
There are public recipient reports of genuine RBS correspondence carrying the address. Royal Bank of Scotland is part of NatWest Group, but an individual letter should still be independently verified.
Does a letter from PO Box 5622 mean I owe money?
No. The return address alone does not establish a debt. Check the contents to determine whether the letter concerns a statement, account update, arrears, debt collection or another matter.
Is M61 0WZ the postcode for PO Box 5622 Manchester?
M61 0WZ is commonly shown alongside the PO Box in public references. Conflicting historical postcode information means it should not be relied upon to decide whether a letter is genuine.

No. A PO Box does not have its own customer-service line. If the letter names NatWest or RBS, use that bank’s current official contact page or mobile application.
What should I do with a PO Box 5622 letter for a previous occupant?
Do not assume the letter concerns you. Leave it unopened, mark it “Not known at this address” or “Return to sender” and repost it. If repeated letters arrive, notify the named bank through its official channels.
