Looking for a month of Xbox Live Gold for your Xbox 360, Xbox One, or Xbox Series X|S? Two listings in the authorized digital games subscriptions space offer the same Microsoft 1 Month Gold Subscription Card (GPC) for $9.99. Both are physical cards - the code is not emailed - and both are for the 1-month code only. The card also works as Game Pass Core or Essential, since Xbox Live Gold has been folded into Microsoft's current subscription naming.
The quick verdict: there is no meaningful functional difference between these two cards. They share the same Microsoft brand, same $9.99 card value, same compatible console list (Xbox 360, Xbox One, Xbox Series S and Series X, and Xbox One X), same New condition, and same country of origin (United States). The only clear differentiators are the MPN and the extra warning note included in each listing.
Here's a side-by-side look at the key details.
| Attribute | Xbox Live 1 Month Gold Card (X18-91639-01) | Xbox Live 1 Month Gold Card (X1775837-01) |
| Price | USD 9.99 | USD 9.99 |
| Brand | Microsoft | Microsoft |
| Card Value | $9.99 | $9.99 |
| Compatible Models | Xbox 360, Xbox One, Xbox Series S\|X, Xbox One X | Xbox 360, Xbox One, Xbox Series S\|X, Xbox One X |
| Condition | New | New |
| Country of Origin | United States | United States |
| MPN | X18-91639-01 | X1775837-01 |
| Extra note | Hulu Plus trial no longer available | Xbox 360 Marketplace closed; avatar items won't work |
Both listings carry the same warning: if you have a Game Pass Ultimate account, this 1-month Gold card will be converted into 14 days of Game Pass Ultimate instead. And both clearly state that Xbox Live Gold is now Game Pass Core/Essential. So if you're hoping for a pure Gold month on an Ultimate account, you'll get half a month of Ultimate instead.
Where each listing stands
There is no *winner* on price, brand, compatibility, or condition. The choice comes down to which extra note you find more useful. The X18-91639-01 listing specifically calls out that the Hulu Plus trial is no longer available and will not work. The X1775837-01 listing specifically warns that the Xbox 360 Marketplace store has closed and avatar items will no longer work. Both are negative restrictions, not bonuses.
If you're buying for online multiplayer or Game Pass access on a modern console, those extra notes are just informational. If you were hoping to use an old Hulu Plus trial or Xbox 360 avatar item, the respective listing makes clear that those perks are gone.
Product notes
#### Xbox Live 1 Month Gold Subscription Card (X18-91639-01)

This is a physical card from Microsoft, priced at $9.99, for 1 month of Xbox Live Gold - now called Game Pass Core or Essential. It works on Xbox 360, Xbox One, Xbox Series S and Series X, and Xbox One X. The listing explicitly says the card is for the 1-month code only and that the code is not emailed; it ships as a physical card. One reason to choose this listing is that it gives you the exact MPN X18-91639-01 if that matters for your records. Its limitation is the included warning that the Hulu Plus trial is no longer available, so don't expect that older perk to work with this card.
#### Xbox Live 1 Month Gold Subscription Card (X1775837-01)

The second listing is the same physical card at the same $9.99 price, also from Microsoft, with the same compatibility list and New condition. It carries the MPN X1775837-01. A concrete reason to choose it: it tells you upfront that the Xbox 360 Marketplace has closed and avatar items will no longer work, so you won't be surprised if you try to use the code for legacy 360 avatar content. Its limitation is that same warning - if you were specifically buying for Xbox 360 avatar items, this card won't deliver that.
Final choice by use case
If you just need one month of online access on any Xbox, either card works. At $9.99, with identical brand, card value, and compatibility, the two are effectively the same. Pick the X18-91639-01 if you want the listing that flags the Hulu Plus trial as unavailable. Pick the X1775837-01 if you want the listing that flags the Xbox 360 Marketplace closure. For everyone else, the choice is a coin flip on the same $9.99 card.
