Can you tell if someone has blocked your texts on their Android phone?

[Android Central Question]

If someone has blocked my number on their android phone, could I tell or will there be a "message failed to send" notice when texting?

Not with regular texting. If you're blocked, it's like sending a letter in the mail and the recipient tossing it in the trash. There is no return to sender or failure notice. Some modern services may offer delivery receipts, but those are not universal.
