Overseas TikTok ads agency for Korean brands

A TikTok Ads Manager account is tied to the country it was registered in, and that registration decides which locations it can target. TikTok says so in its own help centre but never publishes the list. This page sets out what is actually documented for the five markets we run, what is only documented for one placement network, and what is still unverified.

The short answer

The locations a TikTok ad account can target depend on the country the account was registered in, so one Korean-registered account does not reach every market. SELLi is a TikTok strategic partner that runs TikTok advertising in Vietnam, Southeast Asia and Japan on behalf of Korean advertisers, through accounts able to target those markets.

What makes overseas TikTok advertising different

Three things decide whether a campaign can run at all: the account registration country, the advertising law of the target market, and the billing currency and tax treatment. Creative is the last problem, not the first. Korean advertisers usually discover this in the wrong order, after an account has already been created with the wrong currency and time zone.

The Korean-language documents behind each of those three subjects are linked from this page. TikTok ad account country and overseas targeting covers registration and the three routes to delivery; Vietnam’s amended Advertising Law covers the 2026 requirement that offshore advertisers appoint a Vietnamese advertising service provider; agency cost structure separates what TikTok bills from what an agency charges.

Can an account registered in Korea target Vietnam or Japan

TikTok publishes the rule but not the list. Its help centre states that "the available location target options will depend on the country or region you used to register your TikTok Ads Manager account", and the actual per-country list exists only in the Ads Manager dropdown. Answering the question honestly therefore needs both the public documents and a real account.

One TikTok document does enumerate locations by account region: the Pangle placement article. It states that "for self-serve, your account region determines your available locations", and lists the available locations for a Korea-registered self-serve account as Egypt, Indonesia, Kuwait, Malaysia, Morocco, Qatar, Saudi Arabia, South Africa, South Korea, Thailand, Turkey and the UAE. Vietnam and Japan are not on that list.

Five markets, five different sets of conditions

SELLi executes in Vietnam, Japan, Thailand, Indonesia and the Philippines. Malaysia, Singapore and Greater China are not on that list, and there are no pages for them here, because listing a market we cannot execute in costs the advertiser more than admitting it.

Placement availability is read from the Search Ads availability article and the TikTok Lite article; certificate requirements from the SEA/NEA industry table. The Pangle column describes the external app network only.

Location targeting has shared limits too. TikTok does not support location exclusion, allows up to 3,000 locations per ad group, and states that narrow geographic targeting can sharply reduce impressions and clicks and raise cost per action. Delivery accuracy is not guaranteed.

Vietnam changed its advertising law in 2026

Vietnam’s amended Law on Advertising, No. 75/2025/QH15, passed the National Assembly on 16 June 2025 and took effect on 1 January 2026. It requires offshore advertisers promoting goods or services to users in Vietnam through cross-border advertising to engage a Vietnamese advertising service provider and to comply with Vietnamese advertising law.

Offshore advertisers seeking to promote their goods or services to users in Vietnam through cross-border advertising must engage a Vietnamese advertising service provider and adhere to Vietnamese advertising law.

The same amendment introduced an identification-mark duty for online advertising, six duties for advertising conveyors (influencers, KOLs and KOCs, including disclosing the commercial nature before and during the ad), corporate criminal liability, and a 24-hour takedown duty. Anyone running creator seeding into Vietnam is affected directly.

What SELLi does, and where it is

SELLi runs account structure, local-language creative, creator seeding, Spark Ads and reporting. It has three offices, in Incheon, Ho Chi Minh City and Sydney, and the Ho Chi Minh City entity is the local side of the Vietnamese work. Published case material includes a TikTok live commerce campaign for Starbucks Vietnam, referenced only to the extent the case study itself publishes.

TikTok’s only public way to verify a partner claim is its Marketing Partners directory. SELLi states its status here exactly as it is stated elsewhere on this site, as a TikTok strategic partner, and does not claim a badge it cannot link to. How to verify an official TikTok ads agency explains the badge types and the verification route in Korean.

What it costs, and what this page will not tell you

What TikTok bills is public and set out below. What an agency charges is not published here, because it changes with the market, the campaign objective and how much of the creative is produced locally, and a single percentage would mislead more readers than it helped. We scope first and quote in writing.

Campaign minimum budgetTikTokYesAbove 50 USD for both daily and lifetime budgets

TikTok’s official documentation sets no minimum first top-up amount. Figures circulating in the Korean market as a "minimum first deposit" appear to be individual resellers’ own contract minimums, not TikTok policy, and no official source for them has been found.

Every document in this cluster

Twenty-one documents sit under this hub and nothing else in the cluster appears in the site navigation. Seventeen of them are written in Korean only, because the buyer is a Korean company and a machine-translated copy of a legal reference is worth less than no copy at all. The links below resolve to the Korean documents where that is the language they were written in.

Frequently asked questions

Can I target Vietnam with a TikTok ad account registered in another country
TikTok only states that available locations depend on the registration country. It does not publish the list. On the one list it does publish, for the Pangle placement, a Korea-registered self-serve account does not include Vietnam. The in-feed placement has to be checked inside the account, and claiming a flat impossibility would be inaccurate.
Can the country of a TikTok ad account be changed later
No. TikTok states that time zone, region, business name and currency cannot be edited after the account is created. "Changing the account country" is not a feature, so overseas delivery is a question of how the next account is opened.
What is a TikTok agency account
It is an ad account opened under an agency or managed structure rather than self-serve. TikTok’s Pangle document states that managed accounts have a much wider range of available locations than self-serve ones, which is the closest public confirmation that the two differ. The specific entitlements of an agency tier are not published.
Does the Korea-SEA cross-border solution let me advertise in those markets
No. The Korea-SEA and Korea-JP announcements are TikTok Shop commerce solutions that lower the seller-registration bar. Neither announcement lists Ads Manager account creation in scope. A shop opening and an ad account that can target that country are separate things.
How much does SELLi charge
This page does not publish a rate. The structure changes with the market, the objective and how much creative is produced locally, so a single number would mislead. We scope the work and quote in writing, and the cost structure page sets out what the total actually breaks into.
Which languages are these documents written in
This hub is written in Korean and English. The other twenty documents are Korean first, with Vietnamese and Japanese planned for the market pages that local teams actually read. Nothing in this cluster is machine translated.
