1650 Arch Street, Suite 2210, Philadelphia — Who Is Behind That Settlement Letter?
If a letter or postcard tells you to write to “TGG Settlement Administrator,” “Big Bad Cough Settlement,” or another case name at 1650 Arch Street, Suite 2210, Philadelphia, PA 19103 — that address is real. It is the headquarters of Angeion Group LLC, a court-appointed class-action settlement administrator founded in 2013. Angeion usually does not print its own name on the envelope; the return address instead names the specific case or settlement, which is why the address itself, not the company name, is what most people search for. A smaller number of Angeion-related mailings use a different return address entirely — a Baton Rouge, Louisiana P.O. box for one product-liability claims program, and an Everett, Washington address for a notice Angeion sent about its own 2020 data breach.

Who Is Angeion Group?
Angeion Group LLC is a class-action settlement administration company headquartered in Philadelphia. According to its own site, it was founded in 2013 “to bring a more modern approach to class action notice, administration, and payments.” In 2024, Renovus Capital Partners took a majority investment in the company, and Angeion has since folded in three firms whose names may appear on your letter instead of its own: Donlin Recano & Company (acquired 2024, bankruptcy administration), Case Works (acquired 2025, case data management and medical record retrieval), and MedQuest Ltd. (acquired 2026, personal-injury and medical-legal support). Courts appoint firms like Angeion to act as a neutral third party in a class action or mass settlement — sending the legally required notice, running the case website and claim forms, verifying who is eligible, and issuing payments. Getting mail that traces back to Angeion generally means a court case or a company that held your data has your name on its class list — not that you signed up for anything. For how this kind of role works generally, see our settlement administrator hub.
Case Details
Angeion Group LLC headquarters: 1650 Arch Street, Suite 2210, Philadelphia, PA 19103, phone (215) 563-4116, fax 215.525.0209, email info@angeiongroup.com, website angeiongroup.com. The company also lists a New York office at 200 Vesey Street, 24th Floor, New York, NY 10281, and a UK entity, Angeion Group International LLC, at 8 St. James's Square, London, SW1Y 4JU.
The Philadelphia street address is the pattern to know. On every settlement notice we verified, the return address block reads <case or settlement name> / c/o <Case> Settlement Administrator / 1650 Arch St, Suite 2210 / Philadelphia, PA 19103 — the same street address as headquarters, but without the words “Angeion Group” anywhere on it. Examples: “Griffin et al. v. Team Group, Inc., c/o TGG Settlement Administrator, 1650 Arch St, Suite 2210, Philadelphia, PA 19103” and “Big Bad Cough Settlement, Attn: Claim Forms, 1650 Arch St., Ste. 2210, Philadelphia, PA 19103” — the same address also appears on the Non-Drowsy Robitussin Settlement notice. No Philadelphia P.O. box tied to Angeion turned up in the notices we reviewed — only this street suite. This pattern differs from some other administrators, such as Kroll (see our Kroll return-address guide), whose settlement mail tends to carry Kroll's own name.
Two documented exceptions use a different address entirely. The Tyco Fire Products AFFF public water systems settlement, where Angeion serves as notice administrator, sends claims mail to P.O. Box 4466, Baton Rouge, Louisiana 70821. And when Angeion notified people about a 2020 breach of its own systems (see below), that letter's return block read C/O IDX, PO Box 4600, Everett, WA 98204 — mailed through the identity-protection vendor IDX, not from Philadelphia at all. If your letter's address doesn't match any of these, that alone doesn't make it fake — verify the case name instead, using the steps below.
Why Did I Get This Letter?
Less often, the mail is a data-breach notification rather than a settlement, and Angeion is the company reporting the incident, not the administrator. That is what happened in December 2020, when Angeion itself notified people whose data sat in a breached employee mailbox — the letter came through IDX in Everett, Washington, offering free identity monitoring, with no claim form and no payment involved. If your letter offers monitoring enrollment rather than a claim number and a dollar figure, it is almost certainly this second kind, not a settlement payout.
How to Tell a Real Angeion Notice From a Scam
(1) The notice names a real, checkable case — a lawsuit number, a court, and a defendant you can independently confirm through news coverage or a court's own docket. (2) The website it points to matches the case: case sites we have seen named for Angeion-administered cases include teamgroupdramsettlement.com, bigbadcoughsettlement.com, granitewellnessdatasettlement.com and pfaswatersettlement.com. We reached the first three ourselves; pfaswatersettlement.com blocked our request, so we could not check it. Angeion doesn't maintain one public case list, so cross-check the domain against news coverage or the court docket. (3) Filing a claim is free — any request for a processing fee, a gift card, or cryptocurrency is a scam. (4) The return address is plausible: a case name paired with 1650 Arch Street, Suite 2210, Philadelphia, PA 19103 is consistent with verified Angeion mail; a Baton Rouge, LA P.O. box appears only on the AFFF public water systems claims. (5) When in doubt, don't click links in the email or call a number printed only in the message — type the settlement website into your browser yourself, or call Angeion's headquarters at (215) 563-4116 to ask whether the case is one they administer.
How Angeion Pays Out — and What It Doesn't Say
What a real Angeion-administered payout never requires: a fee to release your money, or your online banking login. If a message asks for either, it isn't a legitimate class-action payment, no matter whose name is on it.

One Documented Stumble: Angeion's Own 2020 Data Breach
In July 2020, Angeion discovered that an unknown third party had accessed, without authorization, an employee's corporate email box between March 30 and May 4, 2020. That mailbox held personal information from the firm's own claims administration files — names, dates of birth, signatures, Social Security numbers, driver's license and government ID numbers, medical or health insurance information, and credit card or bank account details. Angeion notified affected people on <strong>December 4, 2020</strong>, offering free identity protection through IDX with an enrollment deadline of March 4, 2021, and filed a copy of the notice with the California Attorney General. Worth knowing: the firm whose business is running other companies' breach notices was, in this instance, the breached company itself — and its own notice letter arrived from a vendor's Washington State address, not from Philadelphia.
Watch Out for These Patterns
Angeion doesn't publish scam warnings aimed at class members on its own site — its fraud-prevention tool, AngeionAffirm, is marketed to law firms to catch false claims, not to consumers checking a letter. That makes it worth knowing the general patterns yourself:
The envelope doesn't say “Angeion” — and that's normal here
Real Angeion mail is usually addressed under a case name (“TGG Settlement Administrator,” “Big Bad Cough Settlement”) rather than “Angeion Group,” so the absence of the company's name on the envelope isn't itself a red flag. It does mean the usual shortcut — searching the sender's name — won't get you far. Search the case name and settlement website instead, and confirm them against a press release or court record before you act on anything in the letter.
A fee, gift cards, or a request for your bank login
No court-appointed administrator, Angeion included, charges class members to file a claim or release a payment. A message asking you to pay something first, or to “confirm” your Social Security number or online banking credentials through a link, is fraud. Report it at ReportFraud.ftc.gov.
A settlement website that isn't the one in official announcements
Type the settlement's web address into your browser yourself rather than clicking a link in an email or text, and match it against the domain named in Angeion's own press release or independent news coverage — for example teamgroupdramsettlement.com or pfaswatersettlement.com. A slightly misspelled or unfamiliar domain claiming to be the same case is the tell.
Angeion Group FAQ
Is Angeion Group legit?
Yes. Angeion Group LLC is a Philadelphia-based class-action settlement administration company founded in 2013, and courts across the country appoint it to run notice, claims, and payments for real cases — including the ones listed above. Separately, the Better Business Bureau profile for Angeion shows a D- rating with 88 complaints filed and notes that the business is not BBB accredited; that reflects service complaints about the administration process, not evidence that the company or a specific settlement is fake.
Why is Angeion Group contacting me about a case I never joined?
Class notice works from the defendant's own records — customer lists, membership data, or the list of people whose information was exposed in a breach — not from sign-ups. If a court ordered notice to everyone in a class and your information was on that underlying list, you get a letter or email whether or not you ever contacted anyone about the case.
My letter says Donlin Recano, Case Works, or MedQuest — is that the same as Angeion?
Yes. Angeion acquired Donlin Recano & Company in 2024 (bankruptcy administration), Case Works in 2025 (case data management and medical record retrieval), and MedQuest Ltd. in 2026 (personal-injury and medical-legal support). All three now operate as part of Angeion Group, so a letter carrying one of those names instead of “Angeion” can still be legitimate Angeion-related mail.
How does Angeion pay out settlements?
Angeion's own site doesn't specify which payment methods it uses case by case — it describes handling “digital payments” broadly and says it distributed more than 10 million of them in 2022. The specific method for your case is listed on that settlement's own official website, not on angeiongroup.com.
Is there one phone number for Angeion Group?
Angeion's headquarters line is (215) 563-4116, but individual settlements run their own toll-free hotlines printed on the notice and case website — for example 866-545-4202 for the Team Group DRAM settlement or 1-855-714-4341 for the AFFF public water systems settlement. Use the number tied to your specific case, not a general search result.
How do I check my claim status with Angeion?
There is no single Angeion claim-status portal. Go directly to the official website named in your notice — for example teamgroupdramsettlement.com for the Team Group case — and use the Claim ID or case number printed on your letter.
I got a check I wasn't expecting that mentions Angeion — should I cash it?
Verify it first. Match the case name on the check to a real settlement using news coverage or the case's official website, then call the hotline printed on that site — not a number on the check itself — to confirm the payment before depositing it.
What does “1650 Arch Street, Suite 2210, Philadelphia” mean on my envelope?
It's Angeion Group's real corporate address, and it's the return address most Angeion-administered settlement notices use — but almost always paired with a case name rather than the word “Angeion,” for example “TGG Settlement Administrator” or “Big Bad Cough Settlement,” both at that same Suite 2210. We found no Philadelphia P.O. box tied to Angeion — only this street suite. Two documented mailings break the pattern entirely: the AFFF public water systems claims program uses P.O. Box 4466, Baton Rouge, Louisiana 70821, and a December 2020 notice about Angeion's own data breach was mailed through the vendor IDX at PO Box 4600, Everett, WA 98204. None of this proves a letter is real or fake by itself — check the case name and settlement website next.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
