> Quick answer: TikTok Ads supports zip code targeting in the US and Canada. Set it at the ad group level in Ads Manager using 5-digit US zip codes. You can add up to 3,000 zip codes per ad group. TikTok does not support zip exclusions or zip+4 format.
Zip code targeting is one of TikTok's most precise location options. Here is how to set it up correctly and get the most from it.

What Is Zip Code Targeting on TikTok Ads?
Definition and hyper-local use case
Zip code targeting lets you show TikTok ads to users in specific postal areas. It goes deeper than city or DMA targeting. Salons, restaurants, law firms, and local service businesses use it to reach nearby customers rather than an entire metro.
When to use zip code vs. city or DMA targeting
City and DMA targeting work well for broad brand awareness. Zip code targeting makes sense when your service area covers only a few neighborhoods. A plumber serving three zip codes does not need the whole city seeing their ads. The SuCo case study published by TikTok For Business found that zip code targeting enabled greater precision than city or DMA options, with faster flexibility as business needs changed.
Supported geographies (US, Canada only)
Per TikTok's Business Help Center, zip code targeting is available in the US and Canada. US advertisers use standard 5-digit zip codes. Canadian advertisers use 3-letter postal codes. Other countries are not supported at this level of granularity.

How to Set Up Zip Code Targeting in TikTok Ads Manager
Step 1: Navigate to the Audience section
Open TikTok Ads Manager. Create or edit a campaign. At the ad group level, scroll to the Audience section. Location targeting lives here, not at the campaign level.
Step 2: Select location targeting
Click the Location field. Choose your target country first. For zip code support, select the United States or Canada. Then switch the targeting granularity to Zip Code.
Step 3: Enter your zip code(s)
You have two options. Search: type each zip code individually and select it from the dropdown. Bulk Upload: paste or upload a list of codes at once. Bulk Upload is the faster path when you are targeting dozens of areas.
Step 4: Confirm targeting limits and review
TikTok allows up to 3,000 location selections per ad group. Review your final list before saving. Ads Manager flags any zip codes unavailable due to policy or regional status. Check the estimated audience size. A very short zip list can shrink delivery significantly.

Key Limitations and Best Practices
No zip+4 support — 5-digit format only
TikTok does not support the extended zip+4 format. US advertisers must enter standard 5-digit codes only. A code like 90210-1234 will not work. Use 90210.
No location exclusion available
TikTok's documentation states the platform does not support location exclusions. You cannot target the US and then exclude specific zip codes. Instead, build your ad group to include only the zip codes you want to reach.
Maximum 3,000 locations per ad group
Each ad group supports up to 3,000 location selections. Most local businesses will never hit this ceiling. Multi-market operators with large coverage areas should plan ad group structure with this cap in mind.
CPA impact of narrow targeting
Narrow zip code targeting reduces your available audience pool. A smaller audience often means fewer impressions and a higher cost per result. Test zip-level targeting alongside a city-level ad group. Compare performance before shifting all budget to the tighter geography.
HEC policy considerations
Advertisers in housing, employment, or credit categories are subject to TikTok's HEC ad policies. These policies may restrict which zip codes are available or how granular targeting can be. Check TikTok's policy documentation if your business falls into one of these categories before launching.

Why Brand Voice Matters in Hyper-Local Campaigns
Tailoring messaging to local audiences
A zip code gets your ad in front of the right area. Your creative and copy close the deal. Local customers respond better when ads feel relevant to their community, not like a recycled national campaign dropped into a new city.

Frequently Asked Questions
Can I exclude zip codes on TikTok Ads?
No. TikTok does not support location exclusions. You cannot target a country and then block specific zip codes. Instead, build your ad group to include only the zip codes you want to reach.
How many zip codes can I add to one TikTok ad group?
TikTok allows up to 3,000 location selections per ad group. For most local businesses this is more than enough, but multi-market advertisers running wide coverage areas should plan their ad group structure around this limit.
Does TikTok zip code targeting work outside the US?
TikTok supports zip code targeting in the US (5-digit format) and Canada (3-letter postal codes). Other countries are not supported at zip code granularity. Use city or DMA targeting for other markets.
Will targeting a small number of zip codes hurt my campaign performance?
It can. A narrow audience pool often reduces impression volume and can raise your cost per result. Test zip-level targeting alongside a city-level ad group and compare CPA before committing your full budget to the tighter geography.
