TikTok reaches 460m users in Southeast Asia, expands in Vietnam

TikTok has reached over 460 million users in Southeast Asia, the company announced at the Apps Summit Southeast Asia in Hanoi, Vietnam.

Indonesia accounts for 160 million users, Vietnam 70 million, and Thailand 50 million, with the remainder across the region.

The company said its platform is now used for app discovery and business growth in areas like gaming, finance, and retail.

At the event, TikTok signed a memorandum of understanding with the Center of Digital Transformation under Vietnam’s Ministry of Culture, Sports and Tourism to support digital transformation, enable cultural exchange, foster digital growth, and help local businesses.

TikTok highlighted its AI-powered creative tools and campaign automation features, citing internal studies showing produced assets achieved 2.6x higher click-through rates and 1.2x higher conversion rates than in-house advertiser creatives.

This partnership signals continued expansion efforts in Southeast Asia, where the company is competing for digital market share.

🧠 Food for thought

Implications, context, and why it matters.

TikTok’s 460M Southeast Asia reach, ad spend, and ROI

  • Onramp Funds, a financing provider for ecommerce sellers, puts Shop-tied ad spend at about $2.1 billion in the region, not TikTok’s full ad take 1.
  • A Marketing Mix Modeling (MMM) study from TikTok found short‑term Return on Ad Spend (ROAS) of 1.7x, or about $1.70 in revenue per $1 spent, about 2x above other measured channels in the test 2. The sample covered 10 Consumer Packaged Goods (CPG) brands in Indonesia and Thailand, so results outside those sectors and markets are unproven 2.
  • In Southeast Asia, TikTok Shop gross merchandise value (GMV) hit $38.2 billion 1. Indonesia’s average order value (AOV) sits near $5 versus about $30 in the U.S. 1. This suggests frequent purchases at lower AOV than in Western markets, with more than 95% of TikTok Shop volume coming from the region 1.

Independent measurement can verify TikTok results for Southeast Asian brands

  • TikTok expanded its Marketing Partner program, which certifies external agencies plus technology partners, adding nine agencies across Southeast Asia with Australia added 3. The company spotlighted AI creative with automation tools, supported by internal performance data showing stronger engagement and conversion outcomes, opening room for mobile attribution with analytics firms such as Adjust or AppsFlyer to offer unbiased measurement 4.
  • Brand teams buy reservation formats that are pre-booked, fixed-price placements 2. Branded Effect, TikTok’s custom augmented reality (AR) effects, returned about $2.3 short‑term ROAS per Nielsen, and brands can commission third‑party studies to verify results 2. TikTok materials list Kantar, Nielsen, Adjust, plus AppsFlyer 4.
  • TikTok says ads drove a 9.4% incremental sales lift when paired with TV for at least four weeks in Southeast Asia 2. Attribution plus media analytics consultancies can win work with cross‑channel Marketing Mix Modeling (MMM) or Multi‑Touch Attribution (MTA) across TikTok with traditional media 2.
