Yes, a blocked number can still try to call and often leave a voicemail, but the call won't ring your phone or notify you; it goes straight to voicemail or is dropped, though they can still try using different methods like hiding their number or VoIP apps to bypass simple blocks.
The only way to see a call history from a blocked number is to unblock the number. They will be added to your regular call list, and you will be able to see any missed calls you receive from the number.
For Android, go to Settings > Call Settings > Additional Settings > Caller ID. Then, select Hide Number. Your calls will remain anonymous and you can bypass the blocked list.
You can tell if someone blocked your number if your calls go straight to voicemail (after one ring), texts show as undelivered (like on WhatsApp), or you're blocked on social media; however, the surest way is to call from another phone: if your calls don't go through from your number but do from another, you're likely blocked, though consistent patterns over time are key to differentiate from normal DND/airplane mode.
When you text someone who blocked you, the message usually sends from your end but is never received by them, with no error message or notification on your phone, though you won't see a "Delivered" status (if your phone usually shows it); it's like sending a message into a void, and you'll never know for sure unless they unblock you or tell you.
This star code will unblock your caller ID for a single outgoing call if you have previously used *61 to block caller ID for all outbound calls.
If the person you're calling has blocked anonymous calls, *67 won't work either. While *67 hides your number from the person you're calling, phone companies can still trace the call.
A blocked number may ring only once and then go to voicemail. (NOTE: It's also possible that the person is on another call, has their phone turned off, has a low battery, or has it set to airplane mode.)
Just like with calls and texts, you won't notify the person you've blocked when they try to FaceTime call you. Instead, they simply won't be able to reach you. From their end, it will appear as though you simply didn't pick up.
Yes, *69 (Star 69) tells you who called by redialing the last number that called you and revealing the number, but it only works if the caller didn't block their ID using features like *67, and its availability depends on your phone carrier and service plan. It's a service that connects you back to the last caller or gives you their number, but modern smartphones often display this in the recent calls log anyway, making *69 less essential now.
Calls go to voicemail
One of the quickest ways to tell if you've been blocked is to call the person you're trying to reach. If the call rings once and then goes to voicemail, this may mean you're blocked.
The simplest and most common way to call someone who's blocked you is by hiding your caller ID. When you do this, your call appears as “Private,” “Unknown,” or “No Caller ID” on the recipient's screen.
It depends on your end goal. If you are doing this to get them back then just ignore. If you just want to move on then block. If your goal is to hurt them, I would advise not to.

Calls go to voicemail after one ring
One of the quickest ways to know if someone has blocked your number is to call them. If your call goes to voicemail after one ring, this could be a sign that your number has been blocked. But, no need to panic just yet.

People aren't notified when you block them.
This Vertical Service Code, *82, enables calling line identification regardless of subscriber preference, dialed to unblock withheld numbers (private callers) in the U.S. on a per-call basis.
6 Ways To Call a Blocked Number
Dialing *77 on your phone activates Anonymous Call Rejection, blocking incoming calls from private or blocked numbers, making anonymous callers hear a message to hang up and try again. It's a landline/VoIP feature (like AT&T, CenturyLink) to stop spam/prank calls but can sometimes vary by carrier or state, potentially connecting to emergency services (like *87 to turn it off).
One effective and ethical way to reach someone who has blocked your primary number is by using Voice-over-IP (VoIP) services or virtual phone numbers. VoIP platforms allow you to make phone calls through the internet, giving you a completely new number that's unaffected by previous blocking.
Can you unblock yourself from someone else's phone? If you have confirmation that someone has blocked your contact on their phone, there's no way to unblock yourself remotely using any of your devices.
