Where to enter your Discover invitation code
The code is printed on the mail piece (wording varies: Invitation Number, offer code, or similar). Typical path:
- Open the URL on the letter—often discover.com/respond, /match, or /myoffer—typed from the letter or via Discover’s official site.
- Enter the invitation / offer code exactly as printed.
- Review intro APR, balance transfer fee, go-to APR, and rewards rules before you continue to a full application.
Credit impact: Viewing a pre-screened offer path is typically a soft check. A hard inquiry generally occurs when you submit the card application.
Code ≠ guaranteed approval: Mail means you were selected under prescreen rules. Final approval and limit still depend on underwriting when you apply.
Are discover.com/respond and /myoffer legit?
Yes. Those paths are official Discover Bank landing pages used for mail and targeted offers (balance transfer promos, cash back products, student variants, etc.). Discover is an FDIC-insured bank brand; the mail channel is normal card marketing.
Phishing still exists elsewhere on the web—stick to the host printed on the letter or navigate from Discover’s main site rather than ads or unexpected SMS links.
What the fine print usually hinges on
| Feature | Headline | What to verify |
|---|---|---|
| Cashback Match | First-year match (product-dependent) | Often a dollar-for-dollar match of cash back after year one under program rules—confirm timing, eligible categories, and that it applies to your product. |
| 0% intro APR | Purchases and/or BTs for N months | Count billing cycles, not “about a year.” Plan payoff before the window ends. |
| Balance transfer fee | Fee % of amount transferred | Commonly about 3% or 5% (minimums may apply). A 0% intro still costs the fee up front—run the math vs your current APR. |
| Go-to APR | Variable after intro | Remaining balances after the intro revolve at the standard variable rate on your account. |
| Annual fee | Often $0 on Discover it consumer cards | Confirm on the Schumer box for the exact card on your letter. |
Balance transfer offers: fee vs interest saved
Mail that leads with 0% intro APR on balance transfers still usually charges a transfer fee. Example framing: moving $5,000 at a 5% fee costs about $250 whether or not interest is $0 during the promo. The deal works only if you would have paid more than that in interest elsewhere and you can clear the balance before the intro ends.

QR code on the Discover letter?
Mail QR codes can include campaign parameters beyond the bare Discover URL. Inspect before you open, or type discover.com/respond (or the exact path on your letter) and enter the invitation code yourself.
