6 Best Phone Number Databases for APAC in 2026 (Mobile-First Coverage)

SyncGTM is the only viable pan-APAC phone data strategy because no single provider covers all four sub-regions adequately. Waterfall enrichment across 50+ data providers lets you chain the best source for each sub-region into one workflow: Ampliz for India, AroundDeal for Southeast Asia, Cognism for ANZ, and global providers for gap-filling — all queried automatically in sequence.

The waterfall is customizable by country. Indian contacts can route through Ampliz first, then SMARTe, then Apollo. Australian contacts can start with Cognism, then RocketReach. Southeast Asian contacts can prioritize AroundDeal. SyncGTM orchestrates this automatically — your reps see one enriched CRM record with the best available number, regardless of which provider found it. Source attribution is included so you can track which providers perform best for each sub-region over time. SyncGTM does not own phone data — it orchestrates access to other providers' databases.

At $99/mo with no per-seat pricing, SyncGTM replaces the need to manage separate subscriptions to three or four regional providers. All enriched data syncs directly to your CRM via HubSpot, Salesforce, Pipedrive, and Attio integrations. For teams building APAC outbound programs that span India through Australia, waterfall enrichment is not a nice-to-have — it is the only approach that achieves acceptable mobile coverage across a region this fragmented.

Ampliz is the clear leader for Indian B2B phone data. With 400M+ APAC records — the majority concentrated in India — Ampliz covers verticals that global providers barely touch: Indian IT services, BFSI, manufacturing, pharmaceutical, and the exploding Indian SaaS ecosystem. Mobile number coverage is the key differentiator: while ZoomInfo might return a switchboard number for an Indian VP, Ampliz returns the mobile number they actually answer.

India: Deepest coverage of any provider tested. Direct dials and mobile numbers for decision-makers across company sizes from startups to Tata-scale conglomerates. Healthcare-specific datasets are particularly strong for pharma and medtech teams targeting Indian hospitals and clinics. Phone accuracy tested at 60-70% for Indian mobile numbers — higher than any global provider achieves for the same market.

Southeast Asia: Secondary coverage includes Singapore, Indonesia, Philippines, Thailand, Vietnam, and Malaysia. Data is sourced from local partnerships and business registries rather than web scraping, giving Ampliz access to contacts that LinkedIn-dependent providers miss. SEA coverage is growing but not as deep as India. ANZ/Japan: Thinner coverage — Ampliz is an India-first provider that is expanding outward, not a global provider adding India. For pan-APAC coverage, pair Ampliz with Cognism (ANZ) or use SyncGTM waterfall enrichment.

AroundDeal fills the Southeast Asian gap that every global provider leaves open. While Ampliz dominates India and Cognism covers ANZ, AroundDeal is the only provider with meaningful phone data across Indonesia, Vietnam, Philippines, Thailand, Malaysia, and Hong Kong. These are the fastest-growing economies in APAC, and AroundDeal has built its database specifically for them.

Southeast Asia: AroundDeal's strongest sub-region. Indonesian tech companies, Philippine BPO firms, Vietnamese manufacturing, Thai conglomerates, and Malaysian financial services are all represented with contact-level mobile data. The Chrome extension pulls numbers from LinkedIn profiles with APAC-optimized data sources — critical because LinkedIn penetration varies wildly across SEA. India: Growing coverage but not as deep as Ampliz. ANZ: Reasonable for Australia, thinner for New Zealand.

Pricing starts at $44/mo for Basic with limited credits, Pro at $88/mo, and Enterprise on custom terms. At these price points, AroundDeal is the most affordable way to test phone outreach in SEA markets. The 43M+ APAC contacts are a fraction of Ampliz's 400M+, but AroundDeal's data is distributed more evenly across SEA countries rather than concentrated in India. For teams targeting the ASEAN economic zone specifically, AroundDeal offers the best coverage-to-cost ratio.

SMARTe built its data model around a simple insight: in APAC, if you do not have the mobile number, you do not have the phone number. While other providers report "phone coverage" that mixes mobiles, landlines, and switchboards, SMARTe specifically prioritizes mobile number verification — because in India, Singapore, and SEA, the mobile is the business line. This mobile-first approach delivers higher actual connect rates than providers with larger databases of mixed-quality numbers.

India: Strong mobile coverage with multi-source cross-referencing. SMARTe's verification process checks numbers against carrier databases, not just web scraping, which catches ported numbers and disconnections faster. ANZ: Competitive coverage for Australia with reasonable accuracy. SEA: Growing but narrower than AroundDeal's dedicated SEA focus. Real-time accuracy scoring lets you see confidence levels before dialing, so reps prioritize high-confidence numbers first.

At $25/mo for Starter, SMARTe is the most affordable APAC phone data option available — less than a single lunch meeting in Singapore. Pro at $49/mo adds more credits and team features. The per-credit cost is low enough to test APAC phone outreach across multiple sub-regions without committing to annual contracts. For budget-conscious teams entering APAC or supplementing a primary provider with additional mobile data, SMARTe offers the best price-to-mobile-coverage ratio in the market.

Cognism brings Diamond Data phone verification to APAC, and it matters most in ANZ where data quality expectations match Western standards. Australian and New Zealand direct dials verified through Cognism's human verification process reach the right person at rates comparable to European data — a significant achievement in a region where most providers struggle to hit 50% accuracy.

ANZ: Cognism's strongest APAC sub-region by a wide margin. Australian enterprise contacts are verified to the same standard as UK data, with Privacy Act compliance built in. Singapore: Growing rapidly as Cognism expands its APAC team. Enterprise and mid-market coverage is competitive. India: Diamond Data verification is extending to Indian contacts, but coverage is still narrower than Ampliz's 400M+ records. Japan/Korea: Minimal useful data — APPI restrictions and cultural barriers limit what any Western provider can offer.

APAC-focused packages start around $25,000/yr with custom configurations. The price is steep, but for teams selling into Australian and Singaporean enterprise accounts, Cognism is the only provider offering human-verified accuracy in these markets. The compliance infrastructure handles Australia's Privacy Act, Singapore's PDPA, and India's DPDPA. For India volume, pair Cognism with Ampliz. For SEA breadth, add AroundDeal. Cognism is the accuracy anchor, not the volume play.

Apollo.io is the lowest-risk entry point for teams testing APAC phone outreach for the first time. At $49/mo with no annual contract on the Basic plan, you can pull Indian, Australian, and Singaporean phone numbers this week and start measuring connect rates against your specific ICP before committing to specialist providers.

India and Australia: Apollo's two strongest APAC markets. Tech, SaaS, and professional services contacts have reasonable phone coverage — expect 50-60% connect rates, well below North American numbers but usable for campaign validation. Singapore: Decent coverage for standard personas. SEA: Sparse. Indonesian, Vietnamese, and Philippine data is minimal. Japan/Korea: Not a viable source. The built-in dialer and email sequences let you run multi-channel campaigns without additional tools.

Apollo's role in an APAC strategy is validation, not scale. Use it to confirm that phone outreach works for your ICP in specific APAC sub-regions. If India converts, upgrade to Ampliz. If ANZ converts, upgrade to Cognism. If you need pan-regional coverage, move to SyncGTM waterfall. Apollo is the $49/mo experiment that tells you where to invest $25,000/yr. No other provider offers that risk-free learning at this price.
