That may or may not be possible. Perhaps the letter has a signature, and if so, you might be able to look up that person on the internet. If the letter has no return address and is also anonymous, then the clues are more subtle. An FBI crime lab might be able to find something, perhaps a fingerprint.
It is the sender of a letter or package's address. It is used just in case the letter or package that is sent does not reach it's destination it can be sent back to the sender.
Yes, a return address is not necessary for delivery as long as the recipient's address is correct and adequate postage is affixed. The return address is only needed if the letter cannot be delivered, so that the sender can get it back and try to fix the problem.
Yes, it will go back to the address
There are two addresses in a business letter. If letterhead is used, that acts as the 'return address' of the sender; if letterhead is not used, the sender's address must be at the top of the letter. Then there is always an 'inside address', the name and/or address of the person or entity that the letter is sent to.
With no RECEIVER address the postal systems won't know where to DELIVER the letter. With no SENDER address the postal systems won't know where to RETURN the letter if the intended receiver moved (and left no forwarding address).
The part of a letter that contains the address of the sender is the letterhead or (for plain paper) return address.The part of a letter that contains the name and address or the address of the recipient is called the inside address.
The return address of a business letter is the address of the sender. Business letters are usually written on letterhead which have the company name and address preprinted on the paper and if that's the case, it's not necessary to also write the return address on the letter. That is also true of envelopes that are preprinted with the company name and address.
The answer depends on the kind of letter. A personal letter may be returned to sender if the residents of the address don't recognize the name of the sender on the return address, if there is a return address. If the recipients recognize the name of the person, they can contact that person for instructions. If the recipient does not know the name, they may contact the sender to investigate. If there is no return address, it can be returned to the postal service, but the postal service will probably send it to 'undeliverable mail' bin. A business letter sent to another business but with a wrong name, will most likely be opened to determine by the contents to whom the letter should be directed internally.
The purpose of a return address stamp is simply to help out the post office. If the letter or parcel cannot be delivered to the address it is being sent to, they can return it to the original sender and they can try to figure out where the person lives or how to get it to them.
Return to sender?
Example: if you send a letter in the mail and if there isn't a stamp, or if the address doesn't exist then they will send it back to you. That's why you pit your address in the upper left corner
A fictitious return address is an address that does not exist or is not associated with the sender. It is often used to conceal the true identity or whereabouts of the sender for privacy or fraudulent purposes. It can be illegal and unethical to use a fictitious return address, especially when sending mail or packages.
