If I had the backup phrase, I wouldn't troubled you mates posting my queries to help me. Actually I was out of my place and had no access to my personal laptop (where I use my usual desktop wallets).. Suddenly I got a call from my friend saying he is in trouble and he suspects that his wallet is hacked and want to transfer his btc to a new wallet and wanted my help. I immediately wanted to create a new wallet with my phone and needed a btc address. So I used blockchain 
I signed up and I got access to my wallet immediately and gave me a btc address. I gave the address to my friend and then the phone was out of battery. When I get back, I came to know he already sent the btc to my new address but I never got any signup email from blockchain with my wallet ID. So I have my email, blockchain password but not the wallet ID. But the thing is I dont get any email when I ask for remind my wallet ID. I dont have the wallet ID and my phone turned off before I check for my backup phrase.

If yes then you are in luck, try this method.
Please note that a new wallet ID will be created once you try to restore your wallet using this method. Also keep your eyes peeled on the official blockchain wallet URL to avoid your credentials getting phished.

If you require urgent access to your funds and are not receiving your authorization emails, you can always use your 12-word backup (recovery) phrase to restore your funds in a new wallet, here: https://login.blockchain.com/#/recover. Please note that imported addresses are not backed up by the backup phrase and will not be restored.
