Yes — we’re going there. Because someone asked, “What the heck are postage stamps, and how do I even use them?” And guess what? That’s a legit question. Because if no one ever showed you, how would you know?

Welcome to Simplify Adulting, where we tackle the real-life stuff no one taught you. Let’s break down the basics of postage stamps: when to use them, when *not* to, and how to make sure your letter actually makes it to where it’s going.

What’s a Postage Stamp?

A postage stamp is proof you’ve paid to mail something. You stick it on an envelope (usually in the top right corner), and the post office knows it’s good to go. But there’s a catch: a single stamp only covers so much — usually about the weight of a basic greeting card (around one ounce).

When a Stamp Works (and When It Doesn’t)

Use a regular stamp when mailing lightweight items such as thank-you cards, letters, invitations, and small flat envelopes.
If your envelope is heavier, thicker, or oddly shaped, or if you’re sending a box, skip the guesswork and head to the post office or a UPS office. They’ll weigh it and charge you the exact amount—no more guessing how many stamps to stack on.

What’s a Forever Stamp?

Postage prices go up. A Forever Stamp means that even if you buy it at today’s rate, it’ll still work in the future — no matter how much prices rise. Think of it like locking in the price now, for whenever you need it later. You can find Forever Stamps at post offices, many grocery stores, Target, or even some pharmacies.

Bonus Tips for Mailing Like a Grown-Up

- Put the recipient’s name and address in the **center** of the envelope.
- Your return address goes in the **top left corner**.
- The **stamp** goes in the **top right** corner.
- Keep a few Forever Stamps on hand — you never know when you’ll need to mail a thank-you note or return something important.
