If you're shopping authorized digital games subscriptions, the Xbox Live Gold 1-Month Card is a straightforward way to add online multiplayer to an Xbox 360, Xbox One, or Xbox Series console. The snag? Two Microsoft cards look exactly alike and cost exactly the same: USD 9.99. The visible difference is the manufacturer part number, X18-91639-01 versus X1775837-01. Both are new, both work on the same Xbox consoles, and both come from Microsoft. This head-to-head lays out what's the same, what's different, and which one to choose.
Quick verdict
Both options are new Microsoft Xbox Live Gold 1-Month Subscription Cards at USD 9.99. They're compatible with Xbox 360, Xbox One, Xbox Series S, Xbox Series X, and Xbox One X, and both have a Card Value of $9.99. If you have a Game Pass Ultimate account, the one-month Gold credit converts into 14 days of Game Pass Ultimate instead of a full month. The cards also note that Xbox Live is now called Game Pass Core/Essential. With the price, brand, condition, and console support all matching, the part number is the only differentiator.

Where each card fits
MPN X18-91639-01: Pick this one if you want the X18-91639-01 part number on your order. It's a new Microsoft card with the same one-month Gold value. The card's note says the Hulu Plus trial is no longer available, so don't expect that extra perk.
MPN X1775837-01: Pick this one if the X1775837-01 part number matches what you're looking for. It's also new from Microsoft. The note on this card calls out the Xbox 360 Marketplace being closed, so avatar items tied to that store won't work.
Since everything else that's listed is the same between the two, the deciding factor comes down to which part number fits your needs.
Xbox Live Gold 1-Month Card (MPN X18-91639-01)
The X18-91639-01 card is easy to choose when you want a single one-month Gold card for an Xbox console. It's new and Microsoft-branded. If you're not using Game Pass Ultimate, this gives you one month of Gold. If you are on Ultimate, it becomes 14 days of Ultimate. The note also makes clear that the Hulu Plus trial is no longer included, so anyone counting on that should look elsewhere. It's a clean match if you just want the card to apply to your Xbox account. For most Xbox owners, this card is the straightforward pick because the part number is the only thing separating it from the other option.
Xbox Live Gold 1-Month Card (MPN X1775837-01)
If you need the X1775837-01 part number specifically, this card delivers the same one-month Gold access. It's also new and Microsoft-branded. The important limitation: the Xbox 360 Marketplace has closed, so avatar items from that store will no longer work. The Gold subscription itself remains usable, but legacy extras won't come back. As with the other card, Game Pass Ultimate members get a 14-day Ultimate conversion instead of a full Gold month. The card also notes that Xbox Live is now part of Game Pass Core/Essential, so the code applies to that current service. If this MPN matches what you need, this version handles the job.
Final choice by use case
- Standard Xbox Live Gold user: Either MPN works. The card provides one month of Gold for online play on your compatible Xbox console.
- Game Pass Ultimate subscriber: Expect the card to convert to 14 days of Game Pass Ultimate.
- Shopper who wants a Hulu Plus trial: Skip this card, because the trial is no longer available.
- Shopper who wants Xbox 360 avatar extras: Don't expect them, because the Xbox 360 Marketplace is closed.
- Shopper with part-number preference: Go with X18-91639-01 if that's the MPN you need; go with X1775837-01 if that's the one you need.
