Have you ever found yourself in a situation where you urgently need to provide your phone number—maybe while signing up for a new app, sharing contact details with friends, or recharging your prepaid account—but simply can’t recall it? You’re not alone! In today’s fast-paced, digital world, people often use multiple SIM cards for different reasons—work, travel, or family. It’s easy to lose track of your own number, especially if you just bought a new SIM card.

If you’re using AIS (Advanced Info Service), Thailand’s largest mobile network, knowing how to check your AIS phone number quickly and reliably can save you from hassle and frustration. This guide covers every method—USSD codes, mobile apps, SIM card packaging, and more—ensuring you never get stuck wondering, “What’s my number?” again.

What Is AIS?

AIS, or Advanced Info Service, is Thailand’s leading mobile network provider. With over 40 million subscribers as of 2024, AIS delivers voice, SMS, and high-speed 4G/5G data services nationwide. It’s known for its extensive coverage, reliable service, and easy-to-use customer support.

Why You Might Forget Your Phone Number

Let’s face it—most of us don’t actually call ourselves. If you recently purchased a new AIS SIM card, switched phones, or use multiple devices, it’s easy to forget your number. Here are some common scenarios:

• You received a new phone number as part of a promotion.

• You’re using a temporary number while in Thailand.

Whatever the reason, not knowing your number can be inconvenient, especially when someone asks for it or when you need to top up.
