I have an RD with the Post Office, which I now realize may have been a mistake. It will mature next year. I added a beneficiary account and attempted a ₹1 transaction, but it failed. The IFSC code provided by the branch staff was IPOS0000DOP, which, according to Groww (https://groww.in/ifsc-code/india-po...ost-office-savings-bank-all-india-single-ifsc), is the IFSC code for Delhi Post office Branch but it shouldn't be the same cause mine is from mumbai. It seems that all Post Office savings accounts might share the same IFSC code, but I cannot find it anywhere on my passbook. so can help me figure out the Right IFSC Code.
