My CoPay wallet shows my Bitcoin Cash address as CTGUTUgVAwHugpf4CyyjAvj8DCFkE4tpEq. What's going on? I thought both Bitcoin and Bitcoin Cash addresses start with 1 or 3?

The previous answer, while correct, is outdated. While BitPay did use a proprietary format early on, we quickly adopted the CashAddr format for Bitcoin Cash/BCH transactions.

Example: bitcoincash:pqkh9ahfj069qv8l6eysyufazpe4fdjq3u4hna323j

You can use our address translator to get the correct format for any address (https://bitpay.github.io/address-translator).

It's a new address format for Bitcoin Cash proposed by BitPay, to prevent BTC/BCC address confusion. It's not widely used, currently.

  • The old addresses that start with 1 (P2PKH) are converted to addresses that start with C

  • The old addresses that start with 3 (P2SH) are converted to addresses that start with H

You can use this "address translator" to translate the addresses: https://bitpay.github.io/address-translator/

  • It’s worth noting that this really should have happened earlier, BCash sharing the version bytes with bitcoin was to intentionally cause confusion. – Anonymous Oct 22 '17 at 8:55
