Nutrition, every record
Allergens
Taco Bell publishes no allergen statement for this item, so it is not offered as free of anything here and sits out of every allergen filter on this site.
By state
The median at the restaurants read in each state. Pick a state at the top of the board and every price on this site prints that state's figure.
What Taco Bell says it is
Taco Bell’s own description on the ordering menu: “Diet Dr Pepper offers the same 23 flavors of regular Dr Pepper, without the calories.”
The two calorie figures
For Diet Dr Pepper the two figures match: both print no calories.
The nutrition menu carries three sizes under this name: 16 fl oz at no calories, 20 fl oz at no calories and 30 fl oz at no calories; the picker above the ticket switches the panel between them. Two notes from the nutrition guide apply to every fountain drink: “Nutrition values for fountain beverages do not account for ice.” “Depending on the sodium content of the water where the beverage is dispensed, the actual sodium content may be higher or lower than the listed values.”
Where it was listed
On 19 September 2026, Diet Dr Pepper was listed at 32 of the 452 restaurants read, in ten states. That makes it a test item, on only a handful of the menus read. Most often in Texas (nine of the ten restaurants read there), Oklahoma (eight of the nine restaurants read there) and Arkansas (six of the eight restaurants read there). States with no listing on the read date are missing from the by-state table above; the table names the ten that had one.
New Mexico had the lowest state median, $2.59; Connecticut the highest, $3.59. A state median stands on ten restaurants at most, so a single expensive or cheap restaurant moves it; the national range is the safer figure. Pick a state on the board or on the prices by state page and the ticket on every page prices its lines at that state’s medians beside the national range.
What the price buys
26th of 35: that is where Diet Dr Pepper sits in Drinks, cheapest first. The section median is $2.99, so it is $0.30 above it.
Taco Bell’s Happier Hour page says: “Get any Regular Freeze or Medium Fountain Drink for just $1 during Happier Hour, every day from 2 to 5 PM at participating locations.” That window is a time-of-day price, not the list price, and it is stated by the brand rather than read from a menu, so it sits in this sentence and not in the range above.
The record against a day
Diet Dr Pepper carries no calories on its record and 95 mg of sodium.
Allergens and certification
Taco Bell publishes no allergen statement for Diet Dr Pepper: it is not in the allergen tool and its record carries no allergen table. This site never marks an item free of anything without a statement, so it sits out of every allergen filter here. The guide’s general note still applies to it: “Peanuts, tree nuts, fish, and shellfish are not used in regular menu items served in Taco Bell restaurants.”
Ways to change it
One add-on is offered; the heaviest is Make it Dirty at no calories. The removable components and what each carries: Ice (no calories). Size prices were read at one restaurants for this page: Small $2.69, Medium $2.99 and Large $3.19. The line’s own range above stands on 32.
The option calories are the ordering menu’s own figures for the option, printed as it prints them; a swapped build is not a nutrition record, so the panel on this page stays the item as published. Option prices were read at one of the restaurants and are printed with that count, never as a national figure.
