PO Box 2000, Chester, PA 19016 — Who It Is and What to Do Next

If PO Box 2000 in Chester, Pennsylvania appears on an envelope or a letter you are holding, it came from TransUnion — one of the three nationwide credit bureaus. Chester is in Delaware County, Pennsylvania, and TransUnion Consumer Solutions handles its written consumer correspondence from there.

Unlike a bank or a collector, TransUnion has no account with you. It holds a file about you and sells reports based on it, which is why a letter can arrive without you having contacted anyone.

The address to use, and the one you may have been given

TransUnion’s own dispute guidance gives the full address as:

TransUnion dispute address	TransUnion Consumer Solutions, P.O. Box 2000, Chester, PA 19016-2000
Consumer phone	800-916-8800

You will also find Chester, PA 19022 printed in older material — the Georgia Attorney General’s consumer pages still list that ZIP code, and it circulates widely in dispute-letter templates. Use 19016-2000, which is what TransUnion publishes today. If you have already posted something to 19022 it has most likely still arrived, but send anything new to the current address and keep the receipt.

Why the letter matters

Two kinds are worth reading closely. The first is the outcome of a dispute you filed: once a bureau tells you its investigation is finished, the deadlines in the Fair Credit Reporting Act start to matter and your options narrow. The second is a notice you never asked for — a fraud alert or freeze confirmation, or a notice referring to an address, employer or account you do not recognize. That second kind often means another person’s information has been attached to your file.

Disputing by mail, and why people still do it

TransUnion accepts disputes online and by phone as well as by post. Posting has one practical advantage: it produces a dated record of exactly what you sent and what you attached, which is the thing that matters if the entry is still wrong afterwards.

Say precisely what is wrong and why, rather than that the report is generally inaccurate. Name the account, the date and the entry. Attach the proof — the paid-in-full letter, the satisfaction of judgment, the docket sheet showing a case was dismissed, identification showing a record belongs to someone else. Include your full name with any middle initial or suffix, date of birth, current address and your addresses for the last two years, because a mismatch on any of those is a common reason files get confused in the first place.

Dispute with the company that supplied the information as well as with TransUnion. Both have duties under the Fair Credit Reporting Act, and disputing only with the bureau is the most common reason a wrong entry reappears.

Send it by a method that produces a receipt. Expect 30 days for the investigation, or 45 if you send more information while it is running. There is no fee.

What usually happens next

We analyzed every credit reporting complaint filed with the Consumer Financial Protection Bureau in the twelve months to 30 June 2026. Of 5,867,288 complaints, roughly a third ended with the entry corrected or removed, about two thirds ended with an explanation and nothing else, and 947 ended with money changing hands — around one in 6,200. TransUnion was named in 2,014,926 of them. The full breakdown is here.

That is not a reason to skip the dispute. Most people who dispute properly get the correction they were after. It is a reason to understand what the process does and does not deliver before relying on it alone.

Frequently asked questions

Is a letter from PO Box 2000, Chester PA a scam?

Chester, Pennsylvania is a genuine TransUnion address and real letters come from there. That does not make every letter using it authentic. If one asks you to call an unfamiliar number or to send money, check independently — use the number published on transunion.com rather than one printed in a letter you were not expecting.

Which ZIP code is correct, 19016 or 19022?

TransUnion publishes 19016-2000. The 19022 version appears in older material and in a great many dispute-letter templates still circulating online. Use the current one.

The same wrong entry is on my other reports. Do I have to dispute separately?

Yes. The bureaus do not correct one another. If it appears on more than one report, dispute with each. Experian’s consumer correspondence comes from Allen, Texas — see PO Box 9701, Allen TX.

What if the account is not mine at all?

Say so in those words, and say whether you believe your file has been mixed with another person’s rather than simply that the account is unfamiliar. Those are investigated differently. Mixed credit files are more common than most people expect.

Can I just call instead?

You can, on 800-916-8800. A phone dispute leaves you without a record of what you said or what you sent, which is the one thing worth having if the entry does not get fixed.

If the dispute does not fix it

The Fair Credit Reporting Act requires a reasonable investigation, not merely a check that the company supplying the information still stands by it. Where that duty is not met, the Act provides for actual damages, and for statutory and punitive damages where the failure is willful. Claims generally must be brought within two years of discovering the violation. Our page on suing TransUnion for a credit report error sets out what a claim has to show.
