To verify a Facebook account right after purchase, check it before doing any work on it: log in through a proxy from the account's region, compare it with the product description, test the bundled email and 2FA, open Ads Manager and look for bans, restrictions or checks. The earlier you catch a problem, the easier it is to show the account arrived that way and get a replacement.
Check the Login First
Start with the login: if the credentials don't work, the account is invalid and there's no point checking anything else.
Use an antidetect browser with a proxy that matches the account's region: a login from another country looks like someone else's, and the platform may block access. If you can't get in, contact support for a replacement right away. More on handling your first auto-reg login in a separate guide.
Watch for red flags: captcha loops or "we noticed unusual activity" messages. They aren't deal-breakers yet, but the account needs careful handling. If Facebook asks for a confirmation code, try to get it through the bundled email; if no code arrives, contact support.
Check Account Details
The account should match the product description: creation date, contact details and bundle contents.
Once logged in, go to Settings > Personal Information. Verify the email and phone number match what came with the account. An auto-reg should show as recently created, and aged stock should match the stated age. An auto-reg is an empty account, so personal photos, posts or a long friends list mean you got a different product. If you bought an auto-reg with a fan page, the page should be in the account.
A ban notice means the account is invalid. A security alert or "account under review" message right away is worth reporting to support with a screenshot.

Test Access to Ads Manager
If Ads Manager loads without errors, the account can run ads; if it shows "you don't have access" or an ad restriction, the account isn't ready for work.
Go to facebook.com/ads/manager. If you're buying FB autoregs for advertising, this is the key check. An Ads Manager that won't load points to restrictions that weren't disclosed.
A verification request (a check) is a different story. A check alone isn't a defect, and auto-regs get one often; here's why fresh auto-regs trigger checks. Try to pass it with the email or phone number from the bundle. If the check doesn't pass within 48 hours, the account qualifies for replacement.

Verify 2FA and Email Access
If the account came with 2FA and an email, make sure both work; without them you don't fully control the account.
Generate a code from the 2FA key in an authenticator app: if 2FA is enabled, you'll need that code at login anyway. If the key is missing or the codes are rejected, that's a legitimate reason for replacement.
Log in to the bundled email and confirm you can read messages. If the mailbox is locked or the password doesn't work, you don't really own the setup. No need to change passwords just to test: changing key details on a fresh account can trigger a check by itself.
Check for Obvious Restrictions
A restriction that has already been lifted is expected on a reinstated (PZRD) account; a new restriction right after purchase is not.
Look through the settings and ad account for ad restrictions, payment method issues or policy violations. PZRD accounts come with lifted restrictions, so a record of that is normal; new ones right after purchase suggest hidden problems.
If a payment method is already attached, check that it's valid: an expired one or one from a different country than expected can cause issues later.

Document Everything
Take screenshots at every step: they are your proof that the account was invalid from the start, not broken by your actions.
Capture the login result, the creation date and any restrictions or checks. If something fails, stop working on the account, describe exactly what's wrong and give the purchase time when you contact support.
If everything checks out (you're in, 2FA works, the email is accessible, Ads Manager opens, no bans), the account is valid. A fresh auto-reg still has low trust, so warm it up before running ads.
FAQ
What should I check after buying a Facebook account?
Log in through a proxy from the account's region, compare the account with the product description, test the bundled email and 2FA key, open Ads Manager and look for bans, restrictions or checks.
Will I get a replacement if the account hits a check?
A check alone isn't a defect: try to pass it with the bundled email or phone number first. If the check doesn't pass within 48 hours, the account qualifies for replacement.
Can I run ads right after verifying an auto-reg?
It's better not to. Even a valid auto-reg is a fresh account with low trust, so warm it up before launching ads.
