What is proof of address?
A proof of address is a document that verifies where you currently reside. It usually features your full name (as it appears on your government-issued ID) and your current address. Common forms include utility bills, bank statements, lease agreements, and official letters from a government agency.
Proof of address documents are often required by banks, financial institutions, and government agencies for identity verification and compliance with anti-money laundering (AML) laws.
Typically, a valid proof of address document should meet the following criteria:
It must display your full legal name and ideally match your government-issued identification, such as your driver’s license or passport.
The address listed on the document should be your current residence.
It must be issued by a recognized entity, such as a government agency, financial institution, utility provider, or established business. It should display the organization’s name, logo, and contact details.
It should be clearly dated and generally issued within the last three months (though some institutions may accept documents up to six or twelve months old, depending on the document type and jurisdiction).
Heads up: Requirements for valid proof of address documents may vary across institutions and jurisdictions.
Examples of valid proof of address
Utility bills
This includes bills from utilities such as electricity, gas, phone, water, or internet. Be aware that the billing address must match the residence address, and certain types of bills (like mobile phone bills) may not be accepted in some jurisdictions.
Bank statements
These include digital or paper bank statements that show essential details such as name and address. Bank statements must typically be from regulated financial institutions, and certain types of bank statements (such as those issued by neobanks) may not be considered valid in some jurisdictions.
Lease agreements
Lease agreements are often valid to prove address or residence; indeed, some jurisdictions and financial institutions explicitly accept them as proof of address. But others may not, as a convincing lease agreement can be easier to forge than other documents.
Government correspondence
Official government letters, such as tax statements or letters concerning social security, voter, or vehicle registration, are almost always considered proof of address.
Documents that don't count as proof of address
Most banks and financial institutions maintain a specific list of accepted documents. It’s best to confirm which documents are acceptable before submitting them. Be aware that the following documents are not generally accepted as proof of address:
Purchase invoices: Standard invoices are often rejected for address or identity verification because they don't come from an official or trusted source.
Unofficial documents: Personal letters or communication that do not originate from an official source (such as those listed above) are unlikely to be recognized.
Photocopies: Originals or certified copies may be required, depending on the institution’s policies.
When applying for a new bank account, an applicant typically needs to prove not only their address, but also their identity. This usually requires submitting two separate documents, as identity cards, passports, and social security cards are usually not accepted as proof of address.
This isn’t always the case. Certain EU countries, for example, may include an address on national ID cards, which can sometimes serve as proof of both identity and address. However, most institutions prefer separate documents for identity and address verification.
Can proof of address be digital?
Yes. A digital proof of address check goes beyond visual confirmation of physical documents and creates a full picture of whether the individual in question is genuine by analyzing metadata, geolocation, and customer identity.
How digital proof of address works
Along with their scanned identity and/or proof of address document, a user is asked to share relevant data points such as device metadata and geolocation, which are then cross-checked for accuracy, in a manner that is compliant with regulations such as GDPR.
There may also be a check to verify that the customer address is residential. Finally, the address is checked against cross-partner and cross-country fraud hotspot databases for known fraud hotspots and suspicious addresses.
Is digital proof of address more secure?
Yes. When properly implemented, digital proof of address solutions can offer enhanced security over traditional document-based checks.
A major flaw in the traditional approach is that many physical address documents are not specifically designed to deter fraud. Traditional checks may also rely on only one or two documents, which may make them more susceptible to fraud.
By contrast, a digital proof of address check leverages multiple data points and fraud detection techniques.
Proof of residency vs. proof of address: Are they the same?
The terms “proof of residency” and “proof of address” are often used interchangeably, but they have distinct meanings.
Proof of residency generally refers to documents that establish a legal or official connection to a location — often for tax, immigration, or school enrollment purposes. These documents confirm where a person lives but may also include more detailed information such as how long they've lived there, whether they own or rent the property, and their connection to the residence — for example, if they are a homeowner or tenant.
Proof of address is simpler. It usually focuses specifically on confirming a person’s current address. Proof includes utility bills, bank statements, lease agreements, or official mail that clearly show the individual’s name alongside the address.
Many documents can serve as both proof of address and proof of residency, depending on the context.
Examples of proof of residency documents
Some official documents that can help establish proof of residency include the following:
Mortgage papers;
Residential lease/property deed;
Tax documents, such as tax returns or property tax statements;
A pension statement, if it includes information about an individual’s relationship to their residence. Some pension documents may not include residency details, in which case they would not be valid for use in this context.
Next-generation fraud detection with Fourthline
Fourthline’s anti-financial crime approach is ongoing, predictive, and powered by machine learning.
Unlike traditional, document-based proof-of-address checks, which rely on static documents that can be easily forged, Fourthline uses geolocation and device intelligence to detect fraud accurately and instantly.
By cross-referencing metadata, device signals, and known fraud patterns, Fourthline enhances address verification beyond what standard documents can provide. This reduces delays and increases conversion rates, all while maintaining compliance with data protection and anti-money laundering regulations.
