Questions

How do I check if a Monero address is valid?

Paste it above. The tool decodes Monero's base58, checks the 4-byte Keccak checksum and the network prefix, and checks that both keys in it are valid curve points — the same checks a wallet makes before sending.

What is an integrated address?

A standard address with an 8-byte payment ID packed into it, 106 characters long, starting with 4 on mainnet. Exchanges used them to tell deposits apart; most now give each customer a subaddress instead.

What is the difference between a subaddress and a standard address?

Both belong to the same wallet. A standard (primary) address starts with 4, subaddresses start with 8. Subaddresses cannot be linked to each other or to the primary address by someone who only sees them.

Is anything I paste sent to your server?

No. The checks run as JavaScript in this page; there is no request when you type. You can load the page and then disconnect from the internet to see for yourself.
