With the evolving world, there might be times when you have to change your basic contact details like address, mobile number, or email id. It is advised to update your details on all the financial accessories like banks, credit cards, utility bills, etc. as soon as possible to continue receiving necessary communications and avoid any delays and frauds. Let’s learn why and how to change credit card mobile number and other details with ease.

Why Is It Necessary to Keep Updated Your Address and Contact Details?

Much importance is paid to updating your KYC (Know Your Customer) these days, especially in the banking sector. It is necessary to protect customers from money fraud. Common KYC details include address, mobile number, and email id. The Banking, Financial Services, and Insurance (BFSI) sector uses these modes to communicate swiftly with their clients through WhatsApp/SMS, email, or physical documents. Even the ‘One Time Password’ (OTP) for secured transactions is communicated through email id or mobile number.

You must keep your address and contact details updated with your credit card issuer for the following reasons:

  • An updated credit card mobile number or email ID ensures that the card issuer can conveniently contact you anytime
  • You get all the information without any lag, especially, OTP needed for transactions
  • Easy and long-lasting access to credit card statements, bank notices, new product information, bill dues, and credit card payment information on email ID and mobile number
  • Updating your credit card address ensures protection from sensitive information theft from someone residing at your old address
  • In case of an issue of a new credit card upon expiry or lost or stolen, it needs to be received by you in person at your current address
  • Timely action on credit card fraud can be taken through the registered mobile number and email ID
