How to write down a phone call

The short answer

Write it up within the hour, while the words are still in your head. Note the date, the time it started, how long it ran, who called whom, and what was said — in their words, not your summary. Then send the other side a short note saying what you understood, and ask them to correct you if you have it wrong. Their reply, or their silence, becomes part of your record either way.

01

The call is the weakest part of anyone's record

A text leaves a text. An email leaves an email. A call leaves nothing.

That matters because the call is usually where the important thing happens. It is where the promise gets made, the amount gets agreed, the complaint gets brushed off, the threat gets delivered. People say things on the phone they would never put in writing, and both sides know it.

Months later there are two versions of that conversation and nothing to separate them. Whoever has to decide it does not have a transcript, and will not get one. What they have is whatever either side wrote down, and when.

02

Within the hour, not at the end of the day

Your memory of a conversation is at its best in the first few minutes and falls away fast. By the evening you remember the gist. By next week you remember how it made you feel. By next month you remember your own version.

So: before the next thing, write it down. Five minutes on your phone in the parking lot is worth more than an hour of careful reconstruction two weeks later.

If you genuinely cannot do it straight away, write it as soon as you can and say when you wrote it. An entry that says "written the following morning" is honest and still useful. An entry that pretends to be same-day is neither.

03

What to write down

Eight things. It takes about three minutes.

  1. 01
    The date, and the time the call started.
  2. 02
    How long it ran. Your phone knows. Check it before you forget.
  3. 03
    Who called whom, and on what number.
  4. 04
    Who you spoke to — name, and their role if they gave it. If they would not give a name, write that down too. It is often the most telling line in the entry.
  5. 05
    Anyone else on the call, on either end.
  6. 06
    What you asked for, in the order you asked.
  7. 07
    What they said, in their words.
  8. 08
    What was agreed, what was refused, and what happens next — including who said they would do it and by when.

Then one line at the bottom: when you wrote this up.

04

Their words, not your summary

This is the part that separates a useful entry from a useless one.

Useless

"Called the office. They were unhelpful and rude."

Useful

"Asked when the plumber would come. She said 'I can't give you a date, we're waiting on the owner.' I asked who the owner was. She said she couldn't tell me. Call ended 11:48."

The second one is shorter to read and does far more work. It contains no opinion at all, which is exactly why a reader believes it. Anybody reading the first version has to take your word for "unhelpful". Nobody has to take your word for a quote with a time on it.

Where you are not sure of the exact words, say so: "words to the effect of" is a perfectly honest thing to write, and it is better than inventing a precise quote you cannot stand behind.

Keep your feelings out of the entry. Not because they do not matter, but because they belong somewhere else. The record is for what happened.

05

The note afterwards is the whole trick

Writing it down privately is good. Sending it to the other side is much better, and it takes two minutes.

After the call, send a short message — email or text, whatever you already use with them:

"Thanks for the call just now. My understanding is that you'll send someone to look at the ceiling next week, and that you'll confirm the day by Friday. If I've got any of that wrong, tell me and I'll correct my record."

That last sentence is doing the work. You are not demanding anything, you are not setting them a deadline, and you are not accusing them of anything. You are offering to be corrected.

If they correct you, you now have their version in writing, which is worth having. If they agree, you have a confirmed account. If they say nothing at all, you have a dated, unchallenged account of the conversation — which is usually the most useful outcome of the three.

This works for the person raising something and the person answering something. It reads as reasonable from either end.

06

On recording the call

People ask this first, so here it is plainly.

The rules on recording a call are different from state to state, and getting it wrong can leave you with a bigger problem than the one you started with. We are not going to tell you what applies where you are, because we would get it wrong for somebody.

What we can say is that a written account, made straight afterwards, needs nobody's permission. It is available to you in every state, on every call, including the one that just ended. It is also what most people end up relying on, because even those who meant to record the important call usually did not have it running when it came.

07

Voicemails, missed calls and the ones you didn't take

These all count, and people forget them.

  1. —
    A voicemail is a record somebody else made for you. Save it. Do not let the phone delete it after thirty days — most do. Write down the date and what it said, and keep the audio if you can.
  2. —
    A missed call is a dated fact. Three missed calls from the same number in one afternoon says something. Screenshot your call log before it rolls over.
  3. —
    A call you chose not to answer is also an entry, and it is better written by you than explained by them later.

08

Where this goes wrong

Six things, all common.

  1. 01
    Writing it up at the end of the week. By then it is a summary of a feeling.
  2. 02
    Recording your conclusion instead of the conversation. "He admitted it was their fault" is your reading. What did he actually say?
  3. 03
    Leaving out the call that went your way. A record with only the bad calls in it reads as a case being built. One with all of them reads as a record.
  4. 04
    Not noting who you spoke to. Six months later, "someone at the office" cannot be followed up by anybody.
  5. 05
    Sorting it out on the phone and leaving it there. The friendliest call of the dispute is the one most worth confirming in writing, because that is where the promise got made.
  6. 06
    Letting the phone delete the evidence. Call logs roll over, voicemails expire. Both are on a clock you did not set.

09

Questions people ask

I didn't write anything down at the time. Is it worth doing now?

Yes. Write it today, and write at the bottom that you are writing it today from memory. A late entry that says it is late is worth far more than no entry, and far more than a late entry pretending otherwise.

What if they say the call never happened?

Your phone's call log has the number, the date and the length. That does not prove what was said, and we are not going to pretend it does. It does settle whether you spoke.

They said one thing on the phone and something different in writing.

Then you have the most useful thing in any record: two accounts from the same person, on dates, that do not match. Keep both. Put them next to each other.

Should I tell them I'm keeping notes?

You don't have to, and the confirming message effectively does it anyway, politely. Most people find the note makes the other side more careful, which is usually to your benefit.
