Missed Call From +255?
Unrecognized international numbers are a common pattern in Wangiri ("one ring") scams: the caller hangs up after one ring hoping you call back a premium-rate number. If you don't know anyone in Tanzania, don't call back. If the call matters, the caller will try again or leave a message.

What does 00255 mean?
00255 is +255 written with the international prefix used in the UK, most of Europe and much of the world: 00 replaces the plus sign, so 00255 and +255 reach the same number in Tanzania. From the US and Canada the prefix is 011, so the same code is written 011 255.

Not necessarily, but treat unexpected international calls with caution. One-ring missed calls are the classic Wangiri callback scam: hoping you return the call to a premium-rate number. If you do not know anyone in Tanzania, do not call back, and never share personal or payment details on calls you did not initiate.
