A caption for the above image.

The phone number 888-899-6650 belongs to Transworld Systems Inc (TSI), one of the largest third-party debt collection agencies operating in the United States. TSI also uses +1 (888) 899-6650 along with dozens of other phone numbers to contact consumers about alleged outstanding debts.

If you see this number repeatedly on your caller ID, TSI has obtained an account they claim you owe. They purchased the debt from a creditor or received authorization to collect on behalf of one.

The calls will not stop until you take specific action.

Is TSI a Legit Debt Collector?

Yes. Transworld Systems Inc operates as a legitimate, licensed debt collection agency. They maintain proper state licensing and follow federal registration requirements. The company has been in business since 1970, giving them over 50 years of experience in the debt collection industry.

However, legitimacy does not equal ethical behavior. TSI has faced numerous legal actions, consumer complaints, and regulatory penalties for violating consumer protection laws.

TSI Legal History and Penalties

TSI, as part of Expert Global Solutions (EGS), agreed to stop harassing debt collection phone calls and paid over $3 million in penalties for FTC violations. This settlement represented the largest penalty ever imposed for such violations at the time.

On September 18, 2017, the Consumer Financial Protection Bureau took action against TSI and the National Collegiate Student Loan Trusts for filing false or misleading affidavits, providing false or misleading testimony, and filing debt collection lawsuits when the companies could not prove the debt was owed.

Justia recorded 67 lawsuits against TSI in one year alleging violations of the Fair Debt Collection Practices Act, and the Consumer Financial Protection Bureau recorded 776 closed Transworld Systems complaints for 2016.

Who Does Transworld Systems Collect For?

TSI works with thousands of creditors across multiple industries. They operate as both a contingency collector (working on behalf of creditors for a percentage) and a debt buyer (purchasing charged-off accounts for pennies on the dollar).

How TSI Acquires Your Debt

Creditors transfer or sell accounts to TSI through two primary methods:

Contingency Collection: The original creditor retains ownership but hires TSI to collect. TSI receives 25% to 50% of recovered amounts. The creditor controls settlement terms.

Debt Purchase: TSI buys portfolios of charged-off debt for 2 to 10 cents per dollar owed. TSI now owns the debt outright and has full control over collection terms. This explains why they accept settlements for 30% to 50% of the balance.

Most creditors attempt internal collection for 90 to 180 days before involving TSI. Once an account reaches TSI, the original creditor considers it a loss and has written it off their books.

What to Do When 888-899-6650 Calls You

What to Do When 888-899-6650 Calls You

Receiving calls from 888-899-6650 requires immediate strategic action. Your response determines whether you resolve the situation or face escalating harassment.

Do Not Ignore the Calls

Ignoring TSI accomplishes nothing positive. The calls continue. They report the debt to credit bureaus. They file lawsuits if the statute of limitations has not expired.

Ignoring also means you miss the 30-day window to request debt validation. This right expires 30 days after TSI's first written contact. After this window closes, they continue collection without proving you owe the debt.

Answer Once to Gather Information

Pick up the phone once. Get basic information:

  • Account number they reference
  • Amount they claim you owe
  • Name of original creditor
  • Date of last payment or charge-off
  • Their mailing address

Tell them you need everything in writing before discussing payment. Do not confirm you owe the debt. Do not make promises to pay. Do not provide bank account information or agree to payment plans.

Send a Debt Validation Letter Immediately

Mail a debt validation letter within 30 days of their first written contact. This forces TSI to prove the debt belongs to you and the amount is accurate.

Debt validation letter example below:


[Your Name]
[Your Address]
[City, State ZIP]

[Date]

Transworld Systems Inc
[Address from their letter]

Re: Account Number [XXXXX]

I dispute this debt in its entirety. Under the Fair Debt Collection Practices Act (15 USC 1692g), I request validation of this debt.

Provide the following:

  • Copy of original signed agreement or contract
  • Itemization of the debt amount including fees and interest
  • Proof you hold legal right to collect this debt
  • Name and address of original creditor
  • Date of last payment or activity on account

Stop all phone contact. Send correspondence to the address above.

[Your Signature]
[Typed Name]

Mail this via certified mail with return receipt requested. Keep copies of everything.


Block 888-899-6650 on Your Phone

While waiting for validation, block the number on your smartphone:

iPhone: Open Phone app, tap Recents, find 888-899-6650, tap the information icon, scroll down, select Block this Caller.

Android: Open Phone app, tap Recent calls, press and hold 888-899-6650, select Block/report spam.

TSI uses multiple phone numbers. Block each one they use to contact you. This reduces stress while you handle the debt through written communication.

Check Your Credit Reports

Pull your credit reports from all three bureaus at annualcreditreport.com. Look for TSI or the original creditor's listing.

Check these details:

  • Date of first delinquency
  • Current balance reported
  • Whether the debt shows as disputed
  • Any other TSI accounts you didn't know about

Dispute any inaccurate information directly with the credit bureaus. TSI must verify the debt within 30 days or the bureaus remove it from your report.

Verify the Statute of Limitations

Check your state's statute of limitations for the debt type. TSI often attempts collection on time-barred debt they have no legal right to sue over.

If the statute of limitations expired, TSI loses the right to sue you in court. They still own the debt. They still call. But they hold no legal enforcement power.

Send a time-barred debt letter:

"This debt exceeds the statute of limitations under [your state] law. I will not make any payment. Stop all contact immediately."

Making even a $1 payment on time-barred debt restarts the statute of limitations in many states. Never pay without confirming the debt's legal status.
