Germans often provide both personal

Step 2: **Line‑Type Detection**. Cross‑reference the first four to six digits against BNetzA allocation tables to mark as geographic, mobile, service, M2M, or personal numbering. Landlines (01, 02, 03, 04, 05, 06, 07, 08, 09—but not 015‑017) cannot receive SMS through standard A2P channels; some CPaaS providers auto‑block them.
Step 3: **HLR Lookup**. Query real‑time mobile subscriber databases through vendors such as Infobip, Sinch, or direct carrier APIs. HLR returns IMSI status (active, suspended, unknown), roaming country, and current MNO. German carriers charge €0.0015–0.0025 per lookup at volume. A dormant or ported‑out SIM yields “absent subscriber”—suppress it to avoid wasted SMS fees and negative deliverability.
Step 4: **MNP Routing**. If you plan to send messages through cost‑optimised SMS hubs, the MNP data allows selection of cheapest route while preserving quality. Telekom numbers sent via a Vodafone route may be penalised as off‑net and blocked.
Step 5: **Consent Match**. Merge with CRM or broker‑supplied france phone number data consent tables. Records lacking proof or older than two years without activity should be set aside unless legitimate interest can be demonstrated.
Step 6: **Deduplication**. and work numbers. Use SHA‑256 hash of E.164 numbers to detect duplicates without exposing plaintext.
Step 7: **Suppression Lists**. Germany lacks a national Do‑Not‑SMS registry analogous to France’s Bloctel, but individual opt‑outs must land on an internal Robinson list and never be contacted again unless new consent arrives. The DDV runs an industry code of conduct with weekly syncs of consumer opt‑out requests; membership obliges honoring them within seven days.
After this pipeline, good‑quality lists achieve <1 percent SMS bounce rate and complaint ratios <0.01 percent—benchmarks carriers use before throttling.
