Collection agencies.
A plain-language guide to the big U.S. debt collectors, debt buyers, and government collection contractors. Use it to figure out who contacted you, what they usually collect, and what to check before you pay anything.
What are the largest debt collection agencies in the U.S.?
The biggest names in U.S. debt collection are large national collectors and debt buyers such as Transworld Systems, Midland Credit Management (Encore Capital Group), and Portfolio Recovery Associates (PRA Group) — companies that collect, buy, or manage consumer debt across the country, on everything from phone and medical bills to credit cards, utilities, and government accounts.
Most collection agencies are private and don't publish their revenue, so no "top 10" list can really rank them by size. Instead, this directory profiles the names people search for and run into most — based on how often they show up on credit reports, collection letters, caller ID, payment portals, and complaint data.
Collection agency, debt buyer, or receivables management company?
The label a company uses changes who owns the account — and what proof to ask for before you pay.
Collection agency
Collects for the original creditor or the current owner of the debt, usually for a fee. It doesn't own your account — so it's worth asking who does.
Debt buyer
Buys the debt outright and collects it for itself. Publicly traded buyers like Encore Capital and PRA Group are among the largest collectors in the country.
Receivables management company
The industry's catch-all term for companies that collect, buy, service, or handle consumer debt. Many of the biggest U.S. collectors describe themselves this way, even though it tells you little about your specific account.

How this list was built
This is an editorial list of the collection companies people are most likely to run into — on letters, calls, credit reports, payment portals, or government programs. It's not a ranking by size, because most of these companies are private and don't publish their revenue. We lean on the companies' own pages for what they do, and on regulator, court, SEC, and complaint records wherever they're available.
Agency profiles
The order reflects how prominent and visible each name is to consumers — not how much money the company makes.
Midland Credit Management (MCM) is the part of Encore Capital Group that deals with consumers directly. Encore buys up old, unpaid debts — often charged-off credit cards — and MCM is the name that then contacts you to collect them.
Portfolio Recovery Associates (PRA) is the consumer-facing name of PRA Group, a publicly traded company that buys large batches of old, unpaid debt and then collects on it directly.

Resurgent manages and collects consumer accounts on behalf of the companies that own them — most often LVNV Funding. So the name on your credit report and the name contacting you may be different.
