1. Nobody was available
The most ordinary reason, and often the easiest to fix. People at work miss day-time deliveries again and again until someone asks about a better time.
"Will someone be home tomorrow, or can a family member accept it?"
An NDR calling service phones the customer after a failed delivery attempt, finds out what really happened and records what to do next, while the courier can still try again. NDR stands for non-delivery report. An AI voice agent can make these calls in the customer's language. This guide covers the 5 common reasons, what to ask for each, a ready script and a planner for any parcel.
NDR stands for non-delivery report: the courier's note that a parcel could not be delivered. That note is short and sometimes wrong, and couriers usually try only a limited number of times before the parcel starts its trip back to you. A call finds out what actually happened while there is still time to act. This is how one can sound when the customer disagrees with the report:
Enter your number and we will set up a live AI demo call for you. Hear the voice, interrupt it, ask it questions, in Hindi or English.
The agent finds out and records. Your team, or your shipping panel, tells the courier what to do.

Each reason needs a different question. A single script that asks "shall we try again?" misses most of what you could fix.
The most ordinary reason, and often the easiest to fix. People at work miss day-time deliveries again and again until someone asks about a better time.
"Will someone be home tomorrow, or can a family member accept it?"
The courier could not find the place, or could not reach the customer to ask. Read the address back and ask for what is missing.
"Could you tell me the flat number and a landmark nearby?"
Do not argue. Find out why, since a wrong item is your problem to solve, while a changed mind is useful to know about your product or your ads.
"May I ask what went wrong with this order?"
Common with cash on delivery, and usually not a refusal at all. State the amount due and ask when it will be easier.
"The amount is [amount]. Which day would suit you for delivery?"
Note it calmly, without blaming anyone, and arrange another try. One case proves nothing, but a pattern by courier or area is worth raising.
"I am sorry about that. I will note it. Shall we send it again?"
Choose the reason and the attempt. The planner shows when to call, what to ask and what your team should do next.
A starting plan: check it against your courier's rules. Nothing is sent or saved.
A message works for buyers who respond to messages. The rest need a call, and sooner is better than later.
| AI call | SMS or chat message | Support team | Leaving it to the courier | |
|---|---|---|---|---|
| Reaches buyers who ignore messages | Yes | No | Yes | Sometimes |
| Finds out the real reason | Yes, by asking | Only if they reply | Yes | Only the report |
| Gets a corrected address | Yes, it notes it | Only if they type it | Yes | Rarely |
| Speaks the buyer's language | 9 Indian languages | One per template | Whoever is on shift | Depends on the rider |
| Copes with a busy day's NDRs | Many calls in parallel | Yes | Only with more people | Not applicable |
| Leaves a record | Recording, transcript, outcome | Reply, if any | Depends on the team | Status update |
| Best for | Every NDR worth saving | A first nudge | Disputes and tricky cases | Nothing urgent |
An NDR is a parcel on a clock. These four habits matter more than clever wording.
Memory of the missed delivery is fresh, and your instruction can still reach the courier in time for the next try.
Courier rules differ, so check your contract. Put the attempt count on your list, so the agent can call the parcels nearest to returning first.
Couriers need instructions by a certain time to act the next day. Plan your calling so that results reach your team before then.
Once a customer has clearly said no, stop calling. Repeat calls about a parcel someone does not want only annoy them.
Start by asking what happened, not by reading the courier's reason. Then record one clear next step.
एजेंट: नमस्ते [नाम] जी, मैं [स्टोर] से बोल रही हूँ। आज आपका पार्सल डिलीवर नहीं हो पाया। क्या बता सकते हैं कि क्या हुआ था?
ग्राहक: मैं घर पर नहीं था।
एजेंट: कोई बात नहीं। कल घर पर कोई रहेगा, या किसी और दिन भेजें?
ग्राहक: कल शाम को रहूँगा।
एजेंट: ठीक है। क्या पता सही है: [पता]? पास का कोई लैंडमार्क भी बता दीजिए।
ग्राहक: [लैंडमार्क] के पास।
एजेंट: धन्यवाद, मैंने नोट कर लिया है। आपकी बात आगे भेज दी गई है।
Agent: Namaste [Name] ji, main [Store] se bol rahi hoon. Aaj aapka parcel deliver nahi ho paya. Kya bata sakte hain kya hua tha?
Customer: Main ghar par nahi tha.
Agent: Koi baat nahi. Kal ghar par koi rahega, ya kisi aur din bhejein?
Customer: Kal shaam ko rahunga.
Agent: Theek hai. Kya pata sahi hai: [Address]? Paas ka koi landmark bhi bata dijiye.
Customer: [Landmark] ke paas.
Agent: Dhanyavaad, maine note kar liya hai. Aapki baat aage bhej di gayi hai.
Agent: Hello [Name], this is [Store]. Your parcel could not be delivered today. Could you tell me what happened?
Customer: I was not at home.
Agent: No problem. Will someone be home tomorrow, or shall we send it another day?
Customer: I will be home tomorrow evening.
Agent: Thank you. Is the address [Address] correct? Could you add a landmark nearby?
Customer: Near [Landmark].
Agent: Thank you, I have noted that and passed it on.
Most of these are quick to decide, and each one prevents a parcel from falling between your team and the courier.

Do not rely on anyone's percentage, ours included. Your own parcels will tell you what the calls are worth.
In the same weeks, call some NDR parcels and leave a similar set uncalled. Then compare how many of each were finally delivered.
Count a parcel only when it has been delivered or returned, because a re-attempt can still fail after a good call.
Address problems and "not at home" should respond better than refusals. If they do not, look at your script and your timing.
Reasons from the calls can show that one courier, area or product causes more failures. That is often worth more than the saved parcels.
Start small so that you can compare results. Most campaigns go live in 24 hours to 7 days.
Tell us how reports reach you, your courier cut-off and who acts on the results.
We write it with you, and the agent calls you for a test in your language.
Call part of your NDR parcels, and leave a similar group uncalled.
Compare final deliveries, read the transcripts and change what did not work.

Fix: a call after the courier's cut-off, or after the final attempt, can no longer save the parcel. Match your calls to the cut-off.
Fix: the report may be wrong. Ask what happened, and leave blame out of it, since you want this person to accept the parcel.
Fix: treat the reason as a starting point. What the customer tells you is often more useful than the status on your panel.
Fix: a new time means nothing until the courier knows. Give one person the job of sending these instructions.
Fix: this call is about a parcel they already ordered. Keep it short and helpful, and leave offers for another time.
एनडीआर यानी नॉन-डिलीवरी रिपोर्ट। जब कूरियर पार्सल नहीं पहुँचा पाता, तो वह एक कारण लिखकर रिपोर्ट करता है। कूरियर कुछ ही बार कोशिश करता है, और उसके बाद पार्सल वापस आ जाता है, जिसका ख़र्च आपको उठाना पड़ता है।
एनडीआर कॉल में एआई एजेंट ग्राहक से पूछता है कि असल में क्या हुआ था, और नया समय या सही पता नोट कर लेता है। फिर आपकी टीम कूरियर को बताती है कि आगे क्या करना है। शुरुआत कुछ पार्सल से कीजिए और देखिए कि कॉल के बाद कितने डिलीवर हुए।
It is a service that calls customers after a failed delivery attempt, finds out what happened and records the next step, such as a new delivery time or a corrected address, so that the courier can try again.
NDR stands for non-delivery report. It is the courier's record that a delivery attempt failed, usually with a short reason such as customer not available.
The same day if possible, inside calling hours of generally 9 AM to 8 PM, and before your courier's cut-off for new instructions.
It varies by courier and contract, and it is usually a small number. Check yours, and add the attempt count to your NDR list so that the last attempts get called first.
You decide how many tries to make and how far apart. After that, the parcel is marked as not reached, so your team can decide what to do.
To begin, no. It records the customer's answer and your team or shipping panel passes it on. A direct link can be looked at after a feasibility check.
It reads the address back and notes the corrected address or landmark in the customer's own words, so that your team can update it.
It can help, because it fixes problems while the courier can still act. It cannot save every parcel. Test it with a called and an uncalled group to see the effect on your own orders.
You can begin with a daily list exported from your panel. A direct link is possible after a feasibility check.
