In the United States, there is no specific “renter identification number” like a Social Security Number or Tax Identification Number (TIN) for renters. However, renters may need to provide certain forms of identification and information when applying for a rental property or signing a lease agreement. Here are some common forms of identification and information that renters may need:

1. Government-Issued ID: Most landlords or property management companies will require renters to provide a government-issued photo ID, such as a driver’s license or passport, as proof of identity.
2. Social Security Number (SSN): Landlords often request the Social Security Number of each tenant as part of the rental application process. This is primarily used for background checks and credit checks.
3. Employment and Income Information: Renters may need to provide proof of employment or income, such as pay stubs or employment verification letters, to demonstrate their ability to pay rent.
4. Rental History: Landlords may ask for information about your rental history, including previous addresses, landlord references, and contact information for previous landlords.
5. Emergency Contact Information: It’s common for rental applications to include a section for emergency contact information in case of emergencies or if the tenant cannot be reached.
6. Personal References: Some landlords may request personal references who can vouch for your character and reliability as a tenant.
7. Application Fee: Landlords often require an application fee to cover the cost of background checks and processing your application.
8. Security Deposit: Renters typically need to provide a security deposit, which is a sum of money held by the landlord to cover any potential damages or unpaid rent during the lease term.
9. Lease Agreement: Once approved, renters will sign a lease agreement that outlines the terms and conditions of the rental, including rent amount, due date, lease duration, and rules and responsibilities.

It’s important to note that the specific requirements and documentation may vary from one landlord or property management company to another. Always check with the landlord or property manager for the exact documentation they require when applying for a rental property.

Additionally, while there is no specific “renter identification number” in the U.S., some states and cities have rental registration or licensing programs that require landlords to register their rental properties with local authorities. These programs are typically designed to ensure that rental properties meet certain safety and code standards and do not pertain directly to renters obtaining an identification number.
