Quick Answer

Bulk SMS for logistics is the automated messaging couriers, 3PLs and fleet operators send at each shipment milestone: booking confirmations as transactional (-T) SMS, and in-transit, out-for-delivery, delivery OTP and failed-attempt updates as service (-S) SMS that reach DND numbers 24/7. Tracking links and callback numbers must be DLT-whitelisted. SMSGatewayHub connects to TMS and WMS platforms through HTTP API and SMPP with a 99.9% uptime SLA.

Logistics messaging at a glance

Most shipment messages are service updates to an existing customer, so they carry a -S header and reach every number around the clock. Only a message that answers the customer's own booking or payment within 30 minutes is -T, and anything that sells is -P.

MessageChannelCategory & suffixWhen to send

Pickup scheduled and picked up from sellerService SMS, WhatsApp utilityService -SWhen the pickup is assigned and completed

Rider dispatch, route and hub alertsSMS over HTTP API or SMPPService -SAt shift start and on route changes

Keep shipment templates purely informational: an offer line turns the message into -P and it loses 24/7 DND delivery. Compare categories on transactional SMS and service explicit vs service implicit SMS.

What changed for logistics messaging

Four rule changes that decide whether tracking SMS and delivery calls get through today.

Shipment updates show -S

Operators now suffix every header, so consignees see AB-XYZEXP-S on delivery updates. Delivery information to an existing customer is a service message; service explicit has been merged into promotional -P.

Tracking links must be whitelisted

Every URL in a message must be a registered CTA and sit in a {#url#} slot. Register your tracking domain, including the dynamic-link format, because unregistered links and public shorteners are blocked at scrubbing.

Callback numbers need {#cbn#}

Rider, hub or masked callback numbers inside an SMS must be whitelisted and tagged {#cbn#}. Rotating masked numbers should come from a registered pool, or use a fixed toll-free number.

1600 and 140 series for calls

TRAI now reserves the 1600 series for service and transactional calls and the 140 series for promotional calls, and is moving business calls off ordinary 10-digit numbers. Plan IVR and delivery-call flows around these series.

SMS vs WhatsApp vs voice for delivery updates: which to use when

SMS is the default for every consignee. Many recipients of a parcel never installed your app and some use basic phones, so out-for-delivery alerts and delivery OTPs go as service (-S) SMS that reach every number, DND included, at any hour. Keep them short, with one whitelisted tracking link and one callback number.

WhatsApp is best when you need an answer back. Utility templates with Reschedule, Change address or Share location buttons turn a failed attempt into a self-service fix, and a reply opens a 24-hour window in which your support team can chat with free-form messages, billed per message. Use WhatsApp alongside SMS, not instead of it.

Voice and missed call cover the rest. An IVR call where the consignee presses a key to choose a new slot works for customers who ignore text, and a missed-call number lets anyone request redelivery without data. RCS adds a branded, verified delivery card with a map on Android, falling back to SMS automatically.

SMSGatewayHub runs all of these from one account, so a single scan event in your TMS can trigger the right channel with fallback. For a broader comparison, read SMS vs RCS vs WhatsApp: which channel is right for your business and see how two-way SMS works under TRAI and DLT.

Frequently Asked Questions

Yes. Shipment status, out-for-delivery and delivery OTP messages are service (-S) SMS to an existing customer, so they reach DND numbers 24/7 as long as they contain no promotional content. SMSGatewayHub registers these templates in the service category and delivers them on its transactional routes.

A delivery OTP sent on the delivery day is delivery information to an existing customer, so it is normally registered as a service (-S) template. A message is transactional (-T) only when it responds to the customer's own action, such as a booking, within 30 minutes. Both categories reach DND numbers at any time.

Register your tracking domain as a whitelisted URL CTA on DLT, including the format for dynamic links, and place the link in a {#url#} slot in the template. Public URL shorteners and unregistered links are blocked at scrubbing. SMSGatewayHub's DLT team whitelists the domain and maps the template for you.

Yes, if the number is whitelisted as a callback CTA and sits in a {#cbn#} slot in the DLT template. For masked or rotating numbers, register the pool in advance or use a fixed toll-free or helpline number. SMSGatewayHub registers callback numbers along with your templates.

Send the delivery window and rider contact on the morning of delivery, and after a failed attempt send a reschedule link, WhatsApp buttons or an IVR call where the consignee picks a new slot. SMSGatewayHub runs SMS, WhatsApp, IVR and missed-call redelivery from one account so the NDR flow reaches the customer on whichever channel they answer.

Your TMS or WMS calls an HTTP API or binds over SMPP whenever a scan event fires, passing the template ID and variables, and receives delivery receipts back. SMSGatewayHub supports HTTP, HTTPS and SMPP connectivity, so high-volume scan traffic can go straight from your system to operators.

Use SMS as the baseline because it reaches every phone without an app or data, and add WhatsApp utility templates when you want buttons such as Reschedule or Share location. Consignees must have opted in to receive WhatsApp updates from your business. SMSGatewayHub can send WhatsApp first and fall back to SMS automatically.
