Find out who actually owns the account.
A collector, servicer, and debt owner are not always the same company. That affects what proof you should ask for.
Possible role: Third-party collector and digital debt-collection provider
Firstsource Advantage says it works with banks and card issuers to resolve past-due debt and that it is a debt collection agency handling accounts on behalf of creditors — so it's collecting for others, not as the owner.
-
Firstsource Advantage says it did not purchase debts on the FAQ page reviewed, so ask which creditor owns or placed the account.
-
Use the creditor name on the notice to confirm whether the account is still with the original creditor or another current creditor.

Start with the facts you can check.
- Firstsource Advantage says consumers can request verification by calling the number on the letter, mailing its 205 Bryant Woods South, Amherst, NY address, or using its contact path.

Confirm the account first.
Even a real collector can have the wrong person, wrong amount, old debt, duplicate placement, or incomplete records.
- The collector name, mailing address, phone number, and website on the letter you received.
- Who the original creditor was, who owns or placed the account now, the account number, balance, and date of last payment.
- Whether the debt may be too old for a lawsuit in your state before you pay or promise to pay.
- Whether the account appears on your official credit reports from AnnualCreditReport.com.
- Whether this looks like the kind of account Firstsource Advantage commonly handles: Credit-card accounts, Financial-institution accounts, Delinquent creditor accounts, Pre-charge-off and post-charge-off collection accounts.
