What NOT to Say If You Answer 888-673-8490
Anything you say to Regional Adjustment Bureau can be used to collect. Protect yourself — avoid these common mistakes on the call.

Don't give bank or card details
Do not read out your bank account, debit, or credit card number to anyone calling from 888-673-8490. Any legitimate Regional Adjustment Bureau resolution can be handled in writing after validation.
Don't confirm personal information
Avoid confirming your SSN, date of birth, employer, or address to the 888-673-8490 caller. If it truly is your Regional Adjustment Bureau account, they should already have what they need and must prove it.

Your Rights When Regional Adjustment Bureau Calls From 888-673-8490
The Fair Debt Collection Practices Act (FDCPA) and Fair Credit Reporting Act (FCRA) give you real leverage. Here is the debt-validation playbook we use at Crowned Credit.
1. Demand Debt Validation (FDCPA §809)
Within 30 days of first contact, send Regional Adjustment Bureau a written debt-validation letter. They must prove the debt is yours, the amount is right, and they have the legal authority to collect — or stop collecting.
2. Dispute With the Bureaus (FCRA §611)
If Regional Adjustment Bureau reported a tradeline, dispute it with Equifax, Experian, and TransUnion. They have 30 days to investigate; unverifiable items must be corrected or deleted.
3. Log the Calls
Write down every call from 888-673-8490: date, time, and what was said. Repeated calls, calls at odd hours, or threats can be FDCPA violations — and leverage for you.
4. Send a Cease-and-Desist
You can demand in writing that Regional Adjustment Bureau stop calling you entirely. The calls must stop, even though they may still report or pursue other legal steps.
5. Check the Statute of Limitations
Every state limits how long a collector can sue on a debt. If the debt is time-barred, Regional Adjustment Bureau generally cannot win a lawsuit — and a payment could dangerously restart that clock.
6. Know the Anti-Harassment Rules
The FDCPA bars Regional Adjustment Bureau from calling before 8am or after 9pm, threatening you, or lying about the debt. Each violation may entitle you to statutory damages.
