Trade Show Booth Numbering: Systems, Conventions and a Worked Example

A booth number is an address. Exhibitors use it on graphics, shipping labels and pre-show emails; visitors use it to find a booth from the directory; the general service contractor uses it to set drape, deliver freight and hang ID signs; your team uses it to sort leads, invoices and complaints. A good scheme lets someone standing in the hall work out where a booth is from its number alone.

• Predictable: the number says which aisle and roughly how far along it
• Stable: numbers don't change after exhibitors have booked
• Expandable: there is room to add booths without renumbering
• Consistent: one format everywhere, from the floor plan to the badge-pickup sign
• Readable: short enough to print large on an aisle sign and say over the phone

This guide covers numbering only. For what each booth type is and how it is priced, see trade show booth types and trade show booth sizes; for laying out the hall itself, see the trade show booth layout guide.

Aisle-based hundreds is the scheme most US trade show visitors already expect, so it is the safe default for an exhibit hall. Sequential numbering is simple to set up but stops working once a floor has more than a few rows: booth 47 could be anywhere. Zone letters work well when the floor is divided by product category, because the letter carries meaning on its own.

1. 1

   Give Each Aisle a Hundreds Series

   Number aisles in the direction visitors walk from the main entrance, usually left to right across the hall: 100, 200, 300 and so on. If the hall has more than nine aisles, carry on to 1000, 1100, 1200, or step by 100 starting from 100 and accept four digits past aisle 900.

2. 2

   Start at the Entrance End

   The booth nearest the entrance gets the lowest number, and numbers rise as you walk into the hall. Visitors then know that 410 is closer to the front than 440.

3. 3

   Split Odd and Even Across the Aisle

   Booths on one side of the aisle take odd numbers and booths on the other take even numbers, so 401 and 402 face each other across the aisle. Keep the same side odd on every aisle.

4. 4

   Number Back-to-Back Rows by the Aisle They Face

   In a back-to-back row, the two halves face different aisles, so they carry different series: the side facing aisle 400 takes 400 numbers, the side facing aisle 500 takes 500 numbers. Booth 412 and booth 513 can share a back wall.

5. 5

   Decide Which Aisle Owns the Corners

   A corner booth takes the number of the aisle its front faces. Peninsulas and end-caps usually take the number of the main aisle they open onto.

6. 6

   Leave Gaps for Expansion

   Where a column, a cross aisle or an empty end of a row might later become booth space, skip the numbers it would take, so new booths slot in without renumbering anything sold.

Here is a small hall with three aisles running away from the entrance and two back-to-back rows between them, plus perimeter rows along the outside walls. Each side has six 10x10 booths. Odd numbers are on the left of each aisle as you walk in, even on the right.

• Booths 102 and 201 share a back wall but sit on different aisles, which is why their numbers differ by aisle, not by one
• A 10x20 covering 205 and 207 is sold as booth 205 (or 205-207), and 207 is not reused
• If an island goes in at the back of aisles 200 and 300, it can take 250 or a separate number such as 1000, and the booths behind it keep their numbers
• If the back of aisle 100 might take two more booths next year, the next show can add 113 and 114 without touching anything else

Pavilions are worth deciding early. If a country pavilion buys 20 booths and resells them, each company inside still needs its own number in the directory, or visitors will be told to find 'the pavilion' and stop there.

The booth number is printed in more places than the floor plan, and every one of them has to match. When you choose a format, check how it looks in each of these before you commit to it.

• Aisle signs: hang the aisle number and the range of booths in it at both ends of each aisle (for example, 400: 401-449). See trade show signage for sizes and placement
• Booth ID signs: the contractor prints the number and company name from your list, so the list must use the same format as the map
• Directory, app and website: visitors should be able to search by booth number and by company name
• Exhibitor emails and portal: exhibitors repeat the number to their own customers, so give it to them in writing as soon as they book
• Shipping labels and freight: the number on the label is what the dock and the drayage crew use to deliver to the booth
• Lead retrieval, invoices and complaints: your team will sort by booth number, so keep it consistent in every export

Layouts change: the venue moves a fire exit, an anchor exhibitor upgrades to an island, a cross aisle is added. The goal is to change as few numbers as possible and to tell everyone who depends on the old ones.

1. 1

   Protect Sold Booths First

   Before sales open, renumber freely. After that, keep the numbers of sold and held booths and only number the new or changed spaces.

2. 2

   Use the Gaps or a Suffix

   New booths take numbers from the gaps you left. If there are no gaps, a suffix such as 412A is better than shifting every booth after 412.

3. 3

   Log and Notify Every Change

   Keep a change log with old number, new number, exhibitor and date. Send each affected exhibitor their old and new number in writing, and ask them to update graphics and labels.

4. 4

   Update Everyone Who Prints the Number

   Send the updated list to the general service contractor, the registration and app team, and anyone printing signage, and republish the floor plan on the same day.

Our blog post on handling floor plan changes without confusing exhibitors and sponsors covers how to announce layout changes more broadly.

Copy this into your exhibitor manual or floor plan notes so the contractor, the app team and exhibitors all work from the same rules.
