This is not required for verification. Verification of a debt involves nothing more than the debt collector confirming in writing that the amount being demanded is what the creditor is claiming is owed; the debt collector is not required to keep detailed files of the alleged debt. Chaudhry v. Gallerizzo, 174 F.3d 394, 406 (4th Cir. 1999).
This provision is not intended to give a debtor a detailed accounting of debt to be collected. Maynard v. Cannon, 401 F. App’x 389, 396 (10th Cir. 2010).
The Eighth Circuit Court of Appeals confirms that the verification requirement is satisfied where the debtor "could sufficiently dispute the payment obligation." See Dunham v. Portfolio Recovery Assocs., LLC, 663 F.3d 997, 1004 (8th Cir.2011).
Proof could consist of:
A credit card statement (such as a charge-off statement) that matches the balance claimed.by the debt collector.
A list of charges that total the amount claimed in the initial communication.
