Turn the box over. Under the marks burnt into the cedar there are two short lines of blue or black ink, stamped a little crooked, and they are the only part of a Habanos box that changes from one box to the next. One line is the date the box was filled. The other is the factory. I read the date on every box I buy and I have stopped reading the factory, and by the end of this piece you will know why. If you just want the answer, type the stamp into our box code decoder and it will give you the month and year. If you want to be able to do it by eye at a counter, which is a much more useful skill, read on.

I wrote a longer piece on every mark on a Cuban box, seals and bands included. This one is only about the ink.

The date, since 2000: three letters and two digits

Every box filled since 2000 carries the same date format: the first three letters of the month in Spanish, then the last two digits of the year. That is all there is to it. The only obstacle for a Swedish or British smoker is that the months are in my language, not yours.

Stamp	Month	Stamp	Month
ENE	January (enero)	JUL	July (julio)
FEB	February (febrero)	AGO	August (agosto)
MAR	March (marzo)	SEP	September (septiembre)
ABR	April (abril)	OCT	October (octubre)
MAY	May (mayo)	NOV	November (noviembre)
JUN	June (junio)	DIC	December (diciembre)

So ABR 24 is April 2024. DIC 19 is December 2019. ENE 00 is January 2000, the first month of the new system. Three of these trip people up every time: ENE looks like it ought to be June and is January; AGO is August, not anything to do with age; DIC is December. You will very occasionally see SET instead of SEP; both spellings of September are used in Cuba and it means the same month.

Sometimes the month and year are stamped as one word, MAY24, sometimes with a space, and sometimes the year sits on the line below. The ink varies from a crisp navy to a smudged grey, because it is a hand stamp applied by someone doing a few hundred boxes a day. A stamp that is too perfect worries me more than one that is slightly crooked.

What the date actually means

The date is the month the box was filled, at the factory, with cigars that had already been rolled and rested. It is not the harvest, and it is not the day the cigars were made.

That matters for two reasons. First, the leaf in a box stamped ABR 24 was picked long before April 2024. Cuban tobacco is fermented and then aged, and the leaf usually rests for a year and a half to two years, the heavier grades longer, before it reaches a roller’s bench. A 2024 box holds tobacco from around 2022. Second, the number that matters for how a cigar will smoke is not the age of the leaf; it is how long the finished cigars have sat together in the cedar. That is the clock the date starts.

My own rule, and it is only mine: I do not open a box of Cubans in its first year. Fresh Habanos, in the six to twelve months after boxing, often go through what smokers call the sick period, where the flavours close up and there is a sharp, almost ammoniac edge on the retrohale. Some boxes never do it; most do a little. From about eighteen months the box settles, and a good vitola from a good year keeps improving for a decade. So when I am choosing between two boxes of the same cigar at the same price, I take the older date every time, and when a shop has a box stamped three years back at the normal price, that is the one I buy. In Sweden and Germany, where stock turns slowly, this happens more often than you would think.

A box you are ageing needs a humidity number you can trust. A Boveda 65% pack and a calibrated digital hygrometer such as the Govee H5075 are enough; the reasons for 65% are in our storage guide.

The date before 2000: a cipher, not a month

Boxes older than 2000 carry a date too, but it is written in a keyword code, and if you buy vintage or inherit a humidor you need to know it.

From 1985, when Cubatabaco first started stamping boxes, until the end of 1998, the date was written with the letters of the word NIVELACUSO. Each letter stands for a digit, one to zero, in order: N is 1, I is 2, V is 3, E is 4, L is 5, A is 6, C is 7, U is 8, S is 9, O is 0. The stamp gives the month, in one or two digits, and then the year in two. So NNSU is 11 98, November 1998. NISU is 12 98, December 1998. NUL, three letters only, is 1 85, January 1985, the first month the system ran. The decoder reads these; type NNSU into it and see.

Then 1999 happened, and this is the year I tell people to be careful with. The keyword was changed at the start of the year, and the two most careful public references do not even agree on what it was changed to: the Cuban Cigar Website records it as CODIGUNETA, Cigar Weekly’s old reference as NETAGIDOCU. About half the factories then switched to something else again mid-year. The honest position on a 1999 box is that the date is uncertain, and a dealer who reads one to you with total confidence is reading a table, not the box. Our decoder tries both keywords and tells you which one it used.

From January 2000 the plain Spanish month came in, and it has not changed since.

Period	How the date is written	Example
1985 – 1998	NIVELACUSO cipher (N=1 … O=0), month then two-digit year	NNSU = November 1998
1999	New keyword, disputed; half the factories changed again mid-year	Read with caution
2000 – today	Three-letter Spanish month, two-digit year	ABR 24 = April 2024

The factory code: what it was, and why I stopped reading it

The second line is the factory code, and here every guide on the internet owes you an apology.

From 1985 to 1998 the factory codes were short and stable and collectors learned them: FPG was Francisco Pérez Germán, the Partagás factory behind the Capitolio; BM was Briones Montoto, the Romeo y Julieta factory; EL was El Laguito, where Cohiba is made; JM was José Martí, the H. Upmann factory. In those years a Cohiba from EL and a Cohiba rolled somewhere else were, in the trade’s opinion, different cigars, and people paid for the letters.

Habanos S.A. changed the codes in 1999, changed them again in 2000, and then in 2003 introduced a fourth system in which the three-letter code is rotated on a schedule the company keeps to itself. There are enough combinations that a code need not repeat for years. The Cuban Cigar Website, which has documented Cuban packaging more carefully than anyone, calls tracking the modern codes virtually impossible. I have never seen a public source that could do it, and I have looked.

So when a website shows you a confident table of “current Habanos factory codes” with EL next to El Laguito, it is showing you the 1985–1998 list under a new heading. When a seller tells you a box stamped 2021 is “from the Partagás factory, you can tell from the code”, he is guessing, or repeating a guess. For any box filled in the last twenty years the factory line tells you one thing only: that someone stamped a three-letter code on it, as Habanos does. That is why our decoder gives you the date and, for the factory, the period a code is known from or a plain “we can’t say”. I would rather the tool be honest than complete.

It matters less than it once did anyway. Since the mid-2000s Habanos has levelled quality control across the Havana factories, and a Cohiba is a Cohiba wherever the box was filled. The date tells you far more about what is inside than the letters next to it.

Reading a stamp at a counter: what I actually do

Here is the sequence, and it takes ten seconds. Turn the box over. Find the two ink lines under the burnt marks. Read the three-letter month and the two-digit year and say the English month to yourself. Count back to today: a box under a year old I will buy to age, not to smoke this week; a box two or three years old at list price is a gift. Glance at the factory line only to see that it exists and looks like a hand stamp, three letters in the same ink as the date.

If there is a small TC near the Totalmente a Mano mark, the box is short filler, tripa corta; Habanos has marked its hand-made short-filler cigars that way since about 2002. Nothing wrong with them, but they are a different, cheaper thing, and the price should say so.

Then, before you pay, check what that vitola costs elsewhere. Every retailer in the Finder is a legal, licensed shop, and the board shows you the spread across Europe for the same box. If the price in front of you is far under the board, the stamp will not save you; the cheapest real Cohiba in Europe still costs what a real Cohiba costs. If the price is right and the date is older than you expected, buy it and thank the shop’s slow turnover.

Can the stamp tell you the box is fake?

No, and I want to be plain about this because the question is usually why people look up box codes at all. A forger copies the stamp from a real box. A date you recognise proves nothing, and a code you do not recognise does not condemn a box either; it may be a period nobody has documented. What a bad stamp can do is confirm a suspicion you already had: a date in a format that did not exist that year (ENE 98 is impossible, because in 1998 the date was still a cipher), a factory code with four letters on a 2020 box, a stamp that is printed flat and perfect rather than inked by hand, or Hecho en Cuba printed rather than burnt. Those are tells. For the seals, the hologram, the barcode on the warranty seal and the rest, read the full box guide. For the honest answer to “is this box real”, the price on the board is still the tell that no forger can fake.

For cigars from an opened box on the road, a sealed case such as the Cigar Caddy holds a humidity pack and survives a suitcase.

Questions I get asked

What does the code on the bottom of a Cuban cigar box mean?

There are two ink lines. One is the date the box was filled, written since 2000 as the first three letters of the Spanish month and the last two digits of the year, so ABR 24 means April 2024. The other is a three-letter factory code that Habanos S.A. has rotated secretly since 2003, so it cannot be decoded for any modern box.

How do I read the date on a Cuban cigar box?

Find the three-letter month under the burnt marks and translate it from Spanish: ENE January, FEB February, MAR March, ABR April, MAY May, JUN June, JUL July, AGO August, SEP (or SET) September, OCT October, NOV November, DIC December. The two digits after it are the year. Our decoder does it for you if you prefer.

Is the box date the harvest year?

No. It is the month the finished cigars were packed into the box. The leaf was harvested and aged for roughly one and a half to two years before rolling, so a box dated 2024 holds tobacco from around 2022.

Which factory codes are on Cuban boxes today?

Nobody outside Habanos S.A. knows. Since 2003 the company rotates the three-letter codes on an unpublished schedule. Tables that list EL, FPG, BM and JM as current are reprinting the 1985–1998 codes; they were accurate then and are not now.

How old should a Cuban cigar box be before you smoke it?

That is opinion, and mine is at least a year after the box date, ideally two. Very fresh Habanos often smoke sharp and closed for their first months. A box two to five years old, kept at 65%, is where most of the cigars I remember have come from.

Does a strange box code mean the cigars are fake?

Not on its own. Codes are copied by forgers and unfamiliar codes exist on real boxes. A date in a format that did not exist in that year is a tell; a code you simply do not recognise is not. Check the burnt marks, the seals and, above all, the price against the Finder.
