Proof of billing is a document that verifies where you live, also known as proof of residence. It is required by banks and other entities as a security measure to ensure that you are not lying about where you live. The document should be issued in your name and match your government-issued identification, contain your current residential address, and be sent by a recognized authority that shows their logo, name, and information. Different types of valid documents can be used as proof of address, such as a utility bill, credit card statement, lease agreement, mortgage statement, or mobile phone bill. If you have no valid document under your name, you may upload a bill named under your parent or spouse, provided you include a supporting document such as your birth certificate or marriage certificate, along with the bill, to validate your relationship with the bill owner.
