Five Guys has brought back its buy-one-get-one burger deal in a short-lived “After Party” promotion, giving customers one last chance on Thursday, March 12, to claim a free burger after the chain’s original 40th birthday offer was overwhelmed by demand.

The revived promotion is available only through online ordering and the Five Guys app at participating U.S. and Canadian locations. Customers must use the code FGAFTERPARTY at checkout to get one free burger of equal or lesser value with the purchase of another burger at regular price.

The New BOGO Offer Is a Redo of February’s Chaotic Promotion

The current Five Guys BOGO deal is not a brand-new campaign. It is a do-over.

The burger chain first ran a buy-one-get-one-free burger promotion on February 17 to celebrate its 40th anniversary, but the turnout was stronger than the company expected. That created long waits, supply problems and widespread customer frustration at some locations.

Five Guys later acknowledged that the birthday promotion did not meet its own standards and said it wanted to make things right. The result was the “40th After Party,” a second version of the BOGO offer running from March 9 through March 12.

How the Five Guys BOGO Deal Works

The mechanics of the offer are simple, but there are a few limits that matter.

Customers must place the order online or through the app rather than in-store. The code FGAFTERPARTY must be entered during checkout. The free item must be a burger of equal or lesser value, and the promotion is limited to one redemption per reward code.

That means the deal is aimed more at digital ordering than walk-in traffic, likely a deliberate choice after the earlier promotion created operational strain in restaurants.

Why Search Interest Spiked This Week

Searches for “Five Guys BOGO” and “Five Guys BOGO deal” have surged because the offer is both time-sensitive and tied to a highly visible apology moment for the brand.

The company turned a promotion problem into a second-chance marketing push, and that helped drive fresh attention from customers who missed the first offer or were frustrated by it. The short redemption window also adds urgency, especially on the final day.

For a brand that does not run value-heavy promotions as often as some fast-food rivals, even a limited burger giveaway becomes a significant search event.

The Deal Ends Thursday

The current Five Guys BOGO promotion runs only through Thursday, March 12.

That makes today the last day for customers to use the code and claim the offer, assuming their local participating restaurant still has availability and normal digital ordering open. The promotion is not positioned as an ongoing value program or a standing weekly special.

So for anyone searching whether Five Guys has a BOGO deal right now, the answer is yes — but only through the end of Thursday, and only through the app or online ordering.

What the Promotion Means for Five Guys

The bigger story behind the offer is how Five Guys responded after a high-profile promotional stumble.

Rather than letting the February backlash linger, the company chose to relaunch the same core deal in a more controlled format. That gives customers another shot at the discount while giving the chain a chance to recover from the original rollout.

For now, the headline is straightforward: Five Guys’ buy-one-get-one burger deal is back, the code is FGAFTERPARTY, and the promotion ends March 12.
