How to Apply for a Supplementary Credit Card in the Philippines

Applying for a credit card for the first time can feel intimidating — but what if you could enjoy the benefits of a credit card without going through the strict approval process? That’s where a supplementary credit card comes in.

Whether you’re a student, freelancer, or new employee, a supplementary card is one of the easiest ways to start building your credit history and enjoy the perks of cashless transactions.

In this guide, we’ll cover:

  • What a supplementary credit card is and how it works
  • The requirements and process for applying
  • The benefits and possible risks
  • Tips to get approved quickly
  • A free tool to calculate potential credit card costs

1. What Is a Supplementary Credit Card? 💳

A supplementary credit card is an additional card linked to the primary cardholder’s account. It’s like a “sub-account” under the main card:

  • The primary cardholder is responsible for paying the total bill.
  • The supplementary cardholder gets to use the card for purchases and bills, but spending is limited by the credit limit set by the bank.

Example Scenario:
Maria owns a BDO credit card with a ₱50,000 credit limit. She gives her son, Kevin, a supplementary card with a ₱10,000 spending limit for school expenses. Maria pays for all transactions, but Kevin gets to enjoy the benefits of a credit card.


2. Why Get a Supplementary Credit Card? 🌟

Supplementary cards are perfect for first-time users because they:

  • Help build your credit history without applying for your own card yet
  • Give you access to cashless payments online and in-store
  • Let you earn rewards points, cashback, or miles (depending on the main card)
  • Often have lower requirements compared to applying for a primary card

If you’re a student, young professional, or someone new to managing finances, this can be your first step into the world of credit cards.


3. Requirements for Applying for a Supplementary Credit Card 📌

Unlike a primary credit card, supplementary cards are easier to get because banks rely on the main cardholder’s income and credit profile.

Basic Requirements:

  • Must be at least 13–18 years old (varies per bank)
  • Must present one valid government-issued ID
  • Must submit a filled-out supplementary card application form
  • The primary cardholder must have an active credit card in good standing

Additional Notes:

  • Some banks allow up to 3–5 supplementary cards per account.
  • The credit limit for the supplementary card is usually decided by the primary cardholder.

4. How to Apply for a Supplementary Credit Card 📝

Here’s a step-by-step guide to help you:

Step 1: Choose the Right Bank & Card

Ask the primary cardholder which bank and credit card benefits suit your needs.

Example:

  • Want cashback? Go for Citi Cash Back or Metrobank Cashback Visa.
  • Want airline miles? Consider PNB Mabuhay Miles or UnionBank Miles+.

Step 2: Prepare the Required Documents

  • Primary cardholder’s valid ID
  • Supplementary cardholder’s valid ID
  • Completed application form
  • Proof of relationship (for dependents, some banks may request a birth certificate)

Step 3: Set a Credit Limit

The primary cardholder decides how much the supplementary cardholder can spend. This helps:

  • Control expenses

  • Manage repayments easily

Step 4: Submit the Application

You can apply through:

  • Bank branches
  • Online applications (many banks now accept digital submissions)
  • Customer service hotlines

Processing usually takes 5–7 banking days.


Step 5: Activate and Start Using Your Card

Once approved, activate the supplementary card through the bank’s:

  • Mobile app
  • Hotline

After activation, you can start shopping, paying bills, and earning rewards!
