P411 (Preferred411) is still online in 2026, and existing members were still using it in 2024. It stopped taking new client and provider applications in April 2018 after FOSTA-SESTA, and nobody has confirmed that it officially reopened to new members. That's exactly what most people searching want to know. Below: how P411 works, what its "OK" system does, what happened after 2018, and what to think about before you rely on it.

What is P411 and how does it work?

P411 is a private screening and verification network for members, not an ad directory. It doesn't show public listings. Members build a verified identity, and providers can give a client an "OK", which is basically a vote from another provider that this client was checked. Other providers can see the OK, so each new booking needs less screening. People often call it a "digital handshake".

To get verified you reportedly need your full name, email and phone, plus photos of a government ID to prove your age, and references from other members. What P411 gives you is trust for people who book regularly, not discovery. It won't show you who's available in your city, it vouches that a client is real. That's a very different job from an open directory, and the pros and cons are on our P411 alternatives page.

What is an "OK" on P411?

The OK is the heart of it. When a provider you've seen gives you one, other providers can see it, so it works like a reference that goes with you everywhere on P411. For regulars that's the big draw: build a good OK history once, and screening with new providers gets quicker because your reputation is already there.

To be clear: an OK is one provider vouching for you, not a criminal background check. P411 doesn't run background checks, and providers themselves often point out that the system shows a client is known and has references, not that anyone formally cleared him.

Is P411 still accepting new members?

That's the open question. After FOSTA-SESTA in April 2018, P411 said it had stopped taking new client and provider applications. It wasn't seized or charged like Backpage, it just closed sign-ups and kept serving existing members. The site is still up in 2026, and provider complaints from 2024 show memberships were active then.

What nobody has confirmed is whether it officially reopened to new members or what it costs now. The last clearly dated statement about sign-ups is from 2018. A basic six-month client membership was reported at around $99 back then, but that's old and may have changed. If you're looking at P411 today, check directly whether they're taking new members before you count on joining.

(Note: there's also a separate site using the P411 name. It's not clear if it's the same people, so don't assume they're the same.)

What about data and privacy?

Because P411 runs on verified identities, it has to collect sensitive information: ID photos and personal details, all held by one company. That's the other side of its screening value, and people in the community have said it straight out. A members-only system shows less publicly than an open directory, but it also puts a very sensitive set of data in one place, and members have to trust that one company to protect it.

This isn't saying P411 has been hacked, there's no sign of that. It's simply the trade-off every ID-based system has, and it's fair to think about it. How different platforms balance verification against keeping as little data as possible is part of our review of verification methods.

What do providers say about P411?

Opinions are mixed. On the good side, P411 is seen as one of the more trusted screening tools in the US, and a lot of people in the community say a P411 OK, together with other signals, is a strong sign that a client is safe and worth the money for screening.

On the critical side, providers and clients talk about hassle: getting in can be slow because you need references, some say the site feels outdated, and people complain about the cost. One provider wrote on a consumer complaint site in 2024 that she was kicked off over a client's disputed report without being able to answer. These are individual stories, not confirmed policy, but they come up often enough that it's good to know.

Frequently asked questions

Is P411 still active in 2026?

The site is online, and existing members were still active in 2024. Whether it takes new members right now isn't confirmed, the last clear statement from 2018 said applications were closed.

Do I need P411 to book an escort?

Not always, but many providers want P411 verification or references before booking. It's one common way to get screened, not something everyone requires.

How do you get verified on P411?

Sign up, send your ID and personal details, and get references or "OKs" from providers. That's if they're taking new applications, which right now isn't confirmed.

Is P411 a background check?

No. It's providers vouching for you through OKs, not a criminal background check. It shows you're known and have references, not that you've been formally cleared.

Is P411 safe to use?

It's built around safety and has a good reputation for it. The main downsides are the hassle and the privacy trade-off of an ID-based system, not any confirmed security problem.

How much does P411 cost?

A basic six-month client membership was reported at about $99 in 2018. Current pricing isn't confirmed and may be different.
