Phone-number answer

Checking a call from Firstsource Advantage?

The published phone numbers below can help you look up the company. Caller ID can be spoofed: a matching number does not authenticate a caller or prove that you owe a debt.

What happened?

Choose the situation that fits. Keep a record as you go.

Wrong person

If the call is for someone else, say they have the wrong person and ask them to stop calling your number. Do not give sensitive identity or financial details to an unverified caller.

Log the date, displayed number, callback number, voicemail, and your request. If the collector claims you owe the debt, use a written dispute explaining that it is not yours.

For a written dispute, use the validation-period end date printed on the notice and keep proof of submission. If you have no notice, request the validation information; do not guess a deadline. A call or log entry does not replace that dispute.

Unfamiliar debt

Ask for written validation information and compare the creditor, account reference, amount, and dates with your records. Do not confirm that you owe it or agree to pay while you are still checking.

An information request is not always a dispute. If you dispute the debt, say so in writing by the notice’s printed validation-period end date and keep proof. If the notice is missing, request it; do not guess a deadline or assume collection must pause.

Received a notice

Save the notice and envelope or original electronic message, and note when it arrived. Check the collector, creditor, itemized amount, account reference, and printed validation-period end date against your records.

If you dispute the debt or amount, send or submit a written dispute on or before that printed end date. Keep a copy and proof of when you sent it. A phone call or call-log entry does not replace a timely written dispute.

Court papers? A validation letter does not replace a court response. Protect the court deadline first.

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.

What official records say.

Each note below comes from a dated government, regulator, court, or SEC record. Use it as background, not as proof about your specific account.

  • The CFPB denied Firstsource Advantage's petition to modify or set aside a civil investigative demand seeking information about debt-collection practices. This was an investigatory public record, not a finding of liability or a consent order.

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.
  • Firstsource Advantage says it does not credit report; if the creditor reports a balance, contact the creditor and use credit-report dispute channels for inaccurate reporting.

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.
